A remarkable discovery answers one of the greatest survival stories in Earth’s history—and a decades-old scientific mystery.
At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...
Between 280 and 200 million years ago, a group of animals evolved which would eventually give rise to mammals, including ...
You can’t make a mammal-ette without laying some eggs. The duck-billed platypus wasn’t the only mammal to lay eggs. Analysis of a fossil in South Africa proves that our mammalian ancestors were ...

CRCHUM researcher Sophie Petropoulos and her team reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of ...
For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...
We often think of the egg-laying reproductive strategy in nature as being employed by birds. Indeed, while many people ...
