Human brains evolved over the last four million years in response to the interaction between environmental challenges and behaviours that enabled us to overcome these challenges. But the future of the brain may be more directly in human hands.
Our ancestors became more successful at ensuring their survival with greater behavioural complexity over time. So their bodies grew in size because of more efficient ways of obtaining foods. And the advantages of greater body size and strength provided security from predator attacks.
As our bodies were growing taller – from about 1.2 metres 3.5 million years ago to about 1.7 metres at the end of the Ice Age some 10,000 years ago, brain expansion followed. This is not surprising because bigger bodies need more nerve cells to control them. But this part may come as a surprise – during the last few thousand years, especially from the time the oldest civilisations arose (about 5,000 years ago) our brains became smaller (yes, smaller!) by about 10%.
This process sped up in the last 2,000 years (see the graph below). If the size of human brain was related to mental ability, this would contradict the increasing sophistication of human knowledge during our recent history.
Recent research suggests that the gene ASPM, which regulates brain growth, is still directing brain evolution. But since the brain is neuro-plastic (changed by learning), in the future it may be enhanced using various biotechnologies. These technologies may include brain-machine interfaces, nootropic substances (drugs for enhancing memory and cognition) and human-non-human gene splicing.
Brain-machine interfaces
Knowledge of how nerve cells communicate with each other to process information in our brains (connecting electric signals by chemicals) can now be used to improve brain function. Electrical interfaces between machines and nerve cells can allow direct input of electronically-processed information into our nervous system. Artificial cochlear implants “talk” to our auditory cortex and the first electronic chips were connected to human visual tracts this year, allowing blind patients to see.
In the future, brain-machine interfaces may offer further improved sensory and cognitive abilities. Futurist thinkers, such as Ray Kurzweil, believe that in the near future neural implants will be so widespread that humans will need them in order to live normally in a high-tech society.
It could even be conceivable that future humans may order “designer label” neural implants that work in tandem with novel virtual reality technologies to produce a kaleidoscope of experiences. Such technologies may provide us with deeper insights into human nature, spirituality and the universe. Just imagine a neural implant working with virtual reality to create fantastical worlds.

Future technologies may also be capable of enhancing alternate forms of communication, such as telepathy. The American Defense Advanced Research Projects Agency (DARPA) is currently in the process of creating a “telepathic helmet” that may offer a technology-based form of telepathic communication between soldiers. If the helmet proves to be successful, it may open the way for the creation of similar telepathic devices that could be used by civilians. These would be veritable “mind machines”!
New nootropics
We also face the prospect of cosmetic neurology – the use of nootropics (drugs that enhance memory or cognitive functions). Mind-enhancing agents such dextro-amphetamine are sometimes used by university students as a study aid, while modafinil is said to improve memory and attention.
Some people in the highly competitive business world are using various nootropics to give them a “mental edge”. While this may be an increasing trend, future-designed nanotechnology-based drugs will offer greater precision and efficiency in stimulating the brain.
Indeed, as precise knowledge of brain functions increases, we may be able to create better nootropics. Such drugs may be able to construct brain molecules or enhance areas of the brain, helping individuals develop new talents and abilities.
The promise of gene technology
Gene therapy in the form of splicing human and animal DNA may provide certain cognitive advantages. According to Oxford scholar Julian Savulescu, splicing human and animal DNA may not only enhance human cognition and perception but will have wider health and social benefits.

We could improve memory function, for instance, by transferring the elephant gene responsible for long-term memory to humans. Similarly, human night vision could be enhanced by splicing owl gene. Such novel splicing could have a number of social implications, from reducing night-time road accidents to assisting rescue teams.
The 21st century and beyond promises an array of novel methods for enhancing human cognition. Perhaps such improvements will enable future humans to find long-lasting solutions to global problems, as well as to go to the stars. Such promises, however, can be fulfilled only if we all value learning and intellectual development over short-term commercial gains.

Arthur and Maciej, thank you for some exciting ideas. Prostheses in advanced forms will certainly take us to the edge of who knows what? Perhaps the enhanced few will have a positive impact on 7 billion people now, and the 9 billion expected soon. One would hope so, anyway. The waiting rooms of oncologists are crowded and waiting lists long already. On the matter of our shrinking brains, I think the dog was our first prothesis (see www.compositeconversationalist.com) and perhaps the dwindling olfactory bulbs explain the shrinking brains.

Look this is where the science community earns the mistrust of the general community, and rightly so I am afraid.
The question the science community should be asking, concerning this, is whether it should be intervening in the human evolutionary process in this way.
Or even if it is really necessary given the enormous environmental and energy problems humanity is facing.
We are already a pill popping society, unnecessarily so in many cases. So is there REALLY any value to society in creating this additional avenue of mass pill popping.
The science community really needs some sort of over arching disciplinary body that directs what research is necessary and/or appropriate.

Greg,
I think you are wrong to believe that those in the scientific community are NOT asking questions about the implications of human enhancement.
There is actually a considerable body of discussion about issues relating to Human Enhancement, the possible benefits and potential pitfalls.
There is much in the writings of the various advocates of human enhancement that gives one pause, and the "yuck" factor which you exhibit is a common and not neccesarily unwarranted response. However…

Geoff I understand that humans have influenced evolution across the board from day dot. From crops, to domesticated animals to ourselves.
But I can't help feeling that this sort of interventon is beginning to cross a threshold. And there is the very simple question as to whether such research is or should be a priority.
My individual skepticism toward such research is probably about as effective as a member of the public criticising the banks about the fees they charge.
What is needed is some sort of body that stands between me and the scientific community and acts as a communication conduit and an enforcement agency. It would need to be independant of both parties......something along the lines of the ACCC perhaps, whose rulings are ignored by scientists at their peril.
Such a body would obviously need representation by scientists, government and the public.

And, I agree with you insofar as this should immediately urge one to caution.
But for the same reason I remain sceptical as to oversight. Who can say what will and will not benefit mankind. Who can say that an oversight committe might not stop research into something that could be of unforseeable utility.

Well put it this way Geoff.
I remember watching doco some where along the line where a scientist had a jar of jelly beans and got a large number of people to guess how many there were.
There were the usual few out of the ball park guesses and a mjority of some where in the ball park guesses. When averaged all the guesses came within a fraction of the correct answer.
I figure that a scientific regulatory body, with all the widely divergent input and complaints it would receive from both inside and outside the scientific community, would end up operting in much the same manor as the above example and give the scientific community the correct direction on average.

Unless they didn't get to see the actual Jar, I am not sure about the analogy. You have some awareness of the capacity of the jar, the layers of jellybeans, the size an so on.
I would say that guessing the future is more like asking people to predict where one particular jellybean will fall when you tip the contents of the jar down the stairs.

The purpose would not to be to predict where the research might end up but rather to prioritise it and constrain it when the majority of society feels it is an inappropriate.
I should add that, for this to work properly, the general public would need to have an adequate level of scientific literacy otherwise you would end up with the likes of the anit-immunisation lobby halting research on vaccines.
And again we return to the inadequacies of our current education system when it comes to science!
George Aranda
Deakin University
Blaming education is an oversimplification. Issues arise as to how science is argued by politics, how the media sensationalises science and how society values science. Studies have shown that simply increasing science literacy doesn't necessarily alter their ideas to be consistent with scientific findings.

You are right of course George that upgrading science education in our schools probably wont have any significant effect the current generations of science illiterates.
But it WILL have a positive effect on the quality of debate about scientific issues in future generations.
Once again your comment is indictative of uncritical short term thinking.
What ever we do, we must always keep in mind what will be the effects on the future or our decisons now.
And baring that in mind, science education reform now is absolutely essential.
Sorry George, but if we don't, then Australian societywill gradually slide towards the low standards of third world countries where superstition, mythology, religion and psuedoscience rule their lives.........and look at the common results of this in their societies!
E.G. Africans hunting and killing albinos for the magical healing properties of their bones etc.

Education is the basis of well informed debate.
So I am not sure there is much that can be done about the high level of scientific ignorance in the current generations.
Unless you can convince all adults, who did not receive a university education, to return to school for the greater good of society.
And convince equally ignorant governments to pay for it.
So we probably have to just endure the current ignorance and hope that education reform will improve matters in the future.

Not sure about that at all.
A few points to consider
1) There is a notable emphasis on eductaion in many of Australia's migrant communities.
2) There is a notable trend of anti-intellectualism within Australians of Anglo-European origin. (I come from the country - I've seen it)
3) In the light of the ethos of individualism, it seems more likely that, rather than decreasing scientific literacy, it is the declining tendency to accept as authoritative statements from people that in previous times were considered figures of authority.
It is not only the Priests and the Politicians that have lost their gravitas.

"There is a notable emphasis on eductaion in many of Australia's migrant communities."

Seriously, I'm a scientist, this is my job. I have spent years in university studying, years as a researcher, I'm even a bona fide 'neuroscientist'. But seriously, "We could improve memory function, for instance, by transferring the elephant gene responsible for long-term memory to humans. Similarly, human night vision could be enhanced by splicing owl gene." Really?! There is absolutely no evidence for this. At all. Full stop. Pure fantasy. Dreamland. On drugs.
How ironic this comes within days of the article by Grant and Menzies on "can you fix the science/soceity divide": https://theconversation.edu.au/help-needed-can-you-fix-the-science-society-divide-8752. Articles like these really aren't helping.

Having recently read some of the musings of the advocates for human enhancement, I would agree with you that a lot of it is 'pie in the sky' sort of stuff.
But it looks like quite a tasty pie. To reduce the entire discussion to ridicule of some of its more speculative pronounccements seems a little un-scientific.
Besides, there is a difference between having no evidence, and there not being any evidence. A little more than a century ago, we had no evidence for a great many things which are now commonly accepted as scientific "truths." That we have no evidence of P does not immediately rule out the possibility of P.
Or, as the Goddess related to Parmenides:
"...that it is not and that it is right that it not be,
this I point out to you is a path wholly inscrutable
for you could not know what is not (for it is not to be accomplished)

I see your point, in that someday it may be possible to do things we think unlikely at the moment. But if you look, for example, at the Olympic games just gone and the constant cycle of new world records, and things like increasing life spans and survival from previously-fatal cancers based on newer medical technologies and drugs, it is obvious that there is already much 'human enhancement' already taking place.
So why not have an article more grounded in reality discussing things actually taking place now? It just seems absurd to post flagrantly 'pie in the sky' ideas, especially when they involve techniques such as splicing human and non-human (note, not 'animal' - we're all animals) DNA when the authors should be well aware of how controversial this is, and how poorly the wider public would view these suggestions

Thanks to the internet, there is ample room for both. Certain physical constraints of old publishing have been removed. Any judgement on what we should therefore discuss is a values argument.
That there is value in a grounded and pragamatic discussion does not negate the value of the speculative. Science proceeds not only by the accumulation of evidence but by the use of imagination…

"We could use DNA from animals to improve humans, providing there was ample debate and research about the safety of doing so, and the public found this acceptable, and that people who signed up for this provided informed consent and were aware of the potential risks and benefits, because after all it could actually just screw up their eyesight" = good scientific writing
"Lets take animal DNA to improve our (already quite excellent) eyesight" = not helpful.

Where is the problem with human genes for memory? Some people have prodigious memories for the most obscure of data and past event.
or gene combinations have been kept in balance through evolution, because too much remembering is usually something of a disability. It stems primarily from a brain unable to prioritise what it has recorded so it becomes cluttered with junk data.

I don't think anyone has claimed that 'splicing' isn't possible - in fact it's part of my day-to-day job! The point is that the suggested modifications are clearly not the result of a single "spliceable" gene, but come from the interplay of numerous genes working in concert during development of the particular organism from its original fertilised egg. Making mice glow is easy* - just introduce a GFP gene. In that case it is a simple one-gene splice.
*By 'easy', I mean the techniques are well understood. Not that it's 'easy' in the 'anyone can do it' sense...

In the same way there are elements that would like to see an end to christmas and easter observances. Not that I celebrate the christian meaning of these myself. But they have become part of the secular culture and people celebrate them whether they are religious or not.

OK so its your wife who is Catholic. I don't care. And I don't care if you think your individual school is acceptable. You give Catholics special exemptions which you are not prepared to give to other religions. Your comment on ethnic minorities is so biased as to be considered reprehensible.
I don't believe ANY religion is entitled to ANY special exemptions in public schools - they interfere with the teaching of science.
Religion is a belief in the supernatural, people coming back from the dead, virgin births, big sky daddies on and on. This has no place in schools.
If any teaching about religion is made in public schools, it needs to be comparative religion - no special exemptions for Catholic or Islam or Caluthumpians.
Comparative teaching of religion - to ensure that students understand the many religions throughout the world and, hopefully, develop understanding of such. Which can be taught under the umbrella of social subjects.

I guess it has its place as a moral code, as long as that is all it is presented as by the chaplains etc. At the same time I would support the introduction of secular ethics classes as an alternative for those who prefer it.

Best of luck to you and especially your children who may or will have to go through the juggling of rationality versus superstition as they mature.
An excellent book I would recommend for you and your children is Sam Harris' "Letter to a Christian Nation."
I have had enough now of trying to show that you are being less than objective regarding the teaching of science in schools.
No doubt we will converse elsewhere on these pages.

"Plenty of people have a highly moral codes who were not schooled in religious schools, attended church, nor, when in need of counsel, had to make do with Christian rather than secular counsellors."
I have pretty much agreed with you Dianan on this. I have merely stated that I don't necessarily have a problem with the chaplains, and muslim equivalents if they exist, for those parents who insist on clinging to their rosaries and Koran.
Depends on how much public money is spent on chaplains as…

Thank you Greg
Read moreYou are right - I became (proudly) an Australian citizen in 1998 (to be pedantic, the correct term should be an "Australian subject" because we are still a monarchy and thus are technically subjects of Her Royal Majesty). In all countries I have lived or worked in I always made a point to respect local culture, to learn local language and customs and to contribute to the local culture and economy.
I have made friends among Aboriginal Australians and did studies of physical growth…

"but children cannot be held responsible for actions of their parents or grandparents"
Perhaps not, but nor can we ignore those attrocities. Individually we are not responsible as we were not around at the time to do anyrhing about it. But our collective society IS responsible and it owes aboriginal society a debt.
" learn language and become useful members of the society where they want to live. We should help them in this process. "

Dear Colleagues
Thankyou for responding to our article. I agree with many of your comments that we need to educate people in science. Transhumanists provide us with a view of a high tech future in which humans will overcome their biological limitations. However, some of these thinkers have little knowledge in evolutionary principles. Eventhough natural selection has been relaxed in Homo, there is micro-evolution still going on. To what degree humans will be able to tinker with future evolution is still to be seen. Early hominins set the stage by using technologies such as tool making and fire use which changed Homo morphology and expedited cultural evolution. We are indeed a species dependent on technology it seems.

Arthur I can't believe you can say "some of these thinkers have little knowledge in evolutionary principles"
then follow it up in the next sentence with, "Eventhough natural selection has been relaxed in Homo, there is micro-evolution still going on"
Natural selection isn't 'relaxed' in our species! If we perfect cloning and only produce exact copies of individuals when they die then we *might* be 'relaxing' natural selection. Otherwise, the gene pool changes from generation to generation - we evolve! Perhaps the details of a few of the minor selective processes are different; being eaten by a predator a lot less common, for example. But the particular selection pressure is irrelevant - the Homo sapiens species continues to evolve under natural selection, just like it always has.
"little knowledge in evolutionary principles" indeed....

Not surprising that human brains have been getting smaller since the last Ice Age. My understanding of research into domestication generally is that most animals' brains diminish when their survival needs are met and they are able to live in a safe environment. Humans are no different. We have become domesticated and therefore the survival drives have diminished because of a generally safer world (except of course when wars occur).
I suspect over time if we continued to live in such security…

This article is loaded with speculations but none receive the critical assessment they deserve. For instance: “The American Defense Advanced Research Projects Agency (DARPA) is currently in the process of creating a “telepathic helmet” that may offer a technology-based form of telepathic communication between soldiers.” This ignores that US and other military research institutions are spending the biggest budgets and scientific effort to enhance human capacities. They want to improve human potential…
