The latest medical scanning technology revealed details of a plesiosaur’s inner ear, showing the extinct marine reptiles swam with their head slightly lowered – unlike the Loch Ness ‘sock puppet’.
A 5-million-year-old fossil that sat collecting dust in a Melbourne museum for more than a century has rewritten the evolutionary history of turtles in prehistoric Australia’s tropical climate.
Early Earth on the left, had seas infused with life-enhancing iron, whereas Earth today, seen on the right, does not.

Life doesn’t just need water and oxygen to thrive, it also needs iron.
Anticipating when cancer cells become resistant to treatment can help oncologists more quickly adjust their therapies.

Applying the principles of ecology and evolution could help oncologists anticipate cancer drug resistance and optimize their treatment plans for patients.
New research in fruit flies elucidates how the genes that direct animal body shape work.

Hox genes make sure all your body parts grow in the right place. Understanding how they work can reveal the process of evolution and lead to potential treatments for congenital birth defects.
Researchers were surprised to find two female condors had managed to hatch chicks that had no fathers. But virgin birth does not seem to produce healthy birds that could strengthen the population.
The genome of the spiny-tailed monitor is divided up into 8 big macochromosomes and 10 tiny microchromosomes huddled in the middle.

Our genomes are built from the tiny chromosomes of a small spineless creature that lived 684 million years ago.

Most modern animals have their roots half a billion years ago in the Cambrian Explosion, but one group was curiously missing from the fossil record - until now.
Bacteriophages are viruses that infect bacteria and play a potential role in the evolution of life.

Viruses have gotten a bad rap for the many illnesses and pandemics they’ve caused. But viruses are also genetic innovators – and possibly the pioneers of using DNA as the genetic blueprint of life.
People navigate cities in much the same way animals navigate their environments.

As you’re walking through city streets on your way to work, school or appointments, you probably feel like you’re taking the most efficient route. Thanks to evolution, you’re probably not.
A recent fossil discovery in the Mackenzie Mountains, NWT may change how we consider animal evolution.

Fossilized comb jellies, or ctenophores, are rare because the creatures are almost completely soft-bodied. Rare fossil finds are helping us learn more about ancient animals and evolution.
Archaehierax sylvestris, whose remains have been unearthed in the arid South Australian outback, was the apex predator in a lush prehistoric forest filled with marsupials and waterfowl.
The researchers found tooth shape varied, depending on the types of food a carnivore regularly bites into – in much the same way we choose a kitchen knife depending on what we’re cutting up.
