As temperatures rise, will species have enough habitat to move to suitable ground?
Animals and plants will need escape hatches to move to cooler climes as the planet warms, but few parts of the U.S. have the natural habitat available for these migrations.
There’s a difference in the sex chromosomes between various mammals, such as the platypus compared to humans.
How new species are created is at the core of the theory of evolution. Mammals may be a good example of how sex chromosome change drove major groups apart.
How many species of frog are in the picture? Genetics often says ‘more than we thought’.
Michael Lee (Flinders University & South Australian Museum)
The Earth is full of many varied species from the largest mammals to the tiniest organisms. But we now think there could be ten times more species than was originally thought.
Some of the many species in the Australian National Insect Collection.
At least 100,000 insects are among the many Australian species still to be formally identified. That's a problem for any biosecurity experts who need to be able to spot potentially invasive bugs.

How did survivors of the Permo-Triassic Mass Extinction adapt to their new, harsh environment? And why is that knowledge so important for modern species?

What scientists first thought was an ancient species that had survived undiscovered for many millions of years, turns out to be part of something equally mysterious.
This massive dragonfly, the Swordbearer Emperor
Anax gladiator, is named for the blade-like spike at its tail tip.

There are 6,000 named dragonfly species worldwide but recently 60 new species were found showing how much more we can learn.
Doing its own thing: the eastern coyote, or coywolf, is a mix of coyote, wolf and dog which has spread across eastern North America.
Jonathan Way, www.EasternCoyoteResearch.com
A wildlife biologist argues that the canid in eastern North America – known as the eastern coyote, or the coywolf by some – deserves to be classified as a separate species.

We've bred them into all shapes and sizes, but dogs haven't been around for long enough to have evolved beyond Canis familiaris.
One of the several precious giant tortoises recently found on Volcano Wolf, Galápagos Islands.
When 100-year-old giant tortoise Lonesome George died in 2012, the world thought his species was lost forever. We went to the Galápagos Islands looking for 'extinct' tortoises – and we found them.
Fragments of woodland surrounded by cleared land in south west Australia.
Australia may have reputation for vast areas of wilderness, but in reality the continent's ecosystems have been chopped and diced. Now we need to protect what's left.
Professor Lee Berger from the University of the Witwatersrand holding the skull of Homo Naledi.
The big question being asked is: where does Homo naledi fit in the evolutionary tree? Assessing the similarity or dissimilarity between fossil skulls has provided a possible clue to the answer.
The skull of Homo naledi is built like those of early Homo species but its brain was just more than half the size of the average ancestor from 2 million years ago.
Despite claims about its age, puzzling combinations of features from Homo naledi gives it an uncanny resemblance to human beings.
Mass extinctions are more complicated than ‘strength in numbers’.
Being big – larger than a dog – increases the risk of being wiped out in a mass extinction.
What’s in a name? Plenty, if it is a dinosaur such as the Changyuraptor, a genus of the ‘four-winged’ predatory dinosaur.
S. Abramowicz, Dinosaur Institute
A dinosaur's name says something about the dinosaur itself. They are grouped together according to similarities they share, which also indicates their ancestral relationships to one another.
This selection of stone tools provides a glimpse into the implements used by Africans 50 000 to 60 000 years ago.
Stone tools have been integral to the way archaeologists have told the human story.
A Steller sea cow skeleton: extinct in 1768.
Analysis of extinction rates over the past centuries shows that humans are causing the sixth mass extinction in the history of the Earth.

Despite its name, the Crimson Rosella is perhaps Australia’s most colour-variable bird and a cause of this striking and beautiful diversity seems to be a disease that’s potentially deadly to many other…
