Watch 👀 as the humerus evolves from an aquatic fish (purple) to a land going tetrapod (orange)!

Research by #mczvertpaleo brings us 'one step' closer to unraveling the tetrapod transition to land. Study shows that changes to the #humerus bone at the origin of limbs altered its function & improved the capacity for limb-based land locomotion. @nature https://t.co/s6mMDqYOU2

For #FossilFriday here is a gif showing how backbone regionalization changed during mammal evolution. The highly modular structure of mammals has allowed them to adapt to diverse environments and move in many different ways. Thanks for paving the way non-mammalian therapsids!
