Fifty years ago this month, evolutionary biologist William Donald Hamilton published a solution to one of biology’s most enduring mysteries: why does altruism exist? Altruistic behaviours are those where…

Ancient remains have confirmed that the face and jaw evolved before the rest of the skull in Neanderthals and early human ancestors. Research conducted at the Sima de los Huesos (Pit of the Bones) archaeological…
One of the most important questions we can ask – and one that continues to take up much of the time of scientists, philosophers and the religious minded alike – is why are humans so different to the rest…
For a biologist like me, the interesting questions about religion have always been where did it come from and why did it evolve? I taught evolutionary biology in a Catholic University in the most Catholic…
About 6,000 years ago, a bacterium underwent a few genetic changes. These allowed it to expand its habitat from the guts of mice to that of fleas. Such changes happen all the time, but in this particular…
Preserved sperm in a shrimp more than 16 million years old has been discovered in Queensland. The finding marks a breakthrough…
Birds may owe their success to the shrinking bodies of their dinosaur ancestors. An international team, led by paleontologist…
Eyes and wings are among the most stunning innovations evolution has created. Remarkably these features have evolved multiple times in different lineages of animals. For instance, the avian ancestors of…
The Conversation organised a public question-and-answer session on Reddit in which Jeremy Pritchard, senior lecturer in biology at the University of Birmingham, explained the science of evolution and tackled…
In a recent paper in Nature, we described a strange marine animal, called Tamisiocaris. They were giants that swam in the oceans over 500 million years ago. They had strange looking appendages on their…
Zebras’ stripes have baffled biologists since Charles Darwin. Many hypotheses have been proposed regarding their purpose but, despite hundreds of years of study, there remains disagreement. In an attempt…
Writing good science exam questions is hard. Getting the wording right, making sure that what you are asking about is clear, pitching the question at the right level, takes time, lots of experience and…
Australia is world famous for its venomous critters, including its many highly venomous snakes. The snake that holds the popular title of “world’s most venomous” is the inland taipan (Oxyuranus microlepidotus…
Evolution of life on Earth began about 3.5 billion years ago but it has not been a constant or continuous process. During the middle years of Earth’s history (1.8 billion to 800 million years ago), evolution…
Despite lack of evidence or logic, some people would like kids to be taught as fact that the Earth was created by a supernatural being some 6,000 years ago. That is the case put forth by Christian Schools…
It’s one of the most tantalising questions in evolutionary biology: how did our aquatic ancestors first move from water onto land? Thanks to research published today in PLOS Biology, new light has been…
Worker ants are a funny old bunch, of many shapes and sizes. But they tend to get bigger and smaller much more often than evolving entirely new shapes, according to a new study. While most animals juggle…
One hectare of land in a tropical forest can hold 650 tree species – more than in all of Canada and the continental US. This has left biologists baffled for decades. Now, with advances in data analysis…
Why help another when you can help yourself? Cooperation is very common in nearly all life, from genes and cells to humans and other animals. However understanding why can be difficult: being selfish seems…
Biological deception, which involves organisms manipulating the behaviour of other animals through the presentation of “false…
