Around 12,440-12,550 years ago, hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephant relatives called gomphotheres...
The evolution of feathers is associated with novel skin ultrastructures, but the fossil record of these changes is poor and thus the critical transition...
A fundamental question in dinosaur evolution is how they adapted to long-term climatic shifts during the Mesozoic Era (the dinosaur era lasting from 230...
