Two fossils found in South Africa provide direct evidence of parental care in extinct pre-mammalian ancestors.
Climate was the main factor that triggered the evolution of warm-bloodedness in mammals and the subsequent mammalian evolutionary success.
A 245m year old fossil is the first evidence that of live births in one of the major groups of animals.
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?
The rise and fall of the essential elements for life could have influenced the way life evolved over many millions of years.
With most species out of the way, remaining plants and animals rush to evolve into the ecological gaps.
The end-Triassic mass extinction may be better known for preceding the rise of the dinosaurs, but it had a profound effect on oceans too.
Newly-discovered fossilised pollen grains found in Swizerland have set the evolution of flowers to 100 million years earlier…
