A Good Science Read: Evolution - from Fossils to Finches

A Good Science Read: Evolution - from Fossils to Finches

SOLVED:Why were the Tiktaalik fossils an exciting discovery for scientists studying tetrapod evolution? a. They are the earliest frog-like animal discovered to date. b. They show that tetrapods successfully colonized land much earlier than previously thought. c. They have a roughly equal combination of fishlike and tetrapod-like characteristics. d. They demonstrate conclusively that limbs evolved as lobe-fins dragged themselves from pond to pond during droughts.

Fossil science Q&A and Thursday BIRDSday (w/ paleontologist Danny Anduza)

YouTubePaleontologizing

When we picture the first tetrapods, or land vertebrates, crawling out of the ocean, we probably imagine they need legs. But evolution also had to bestow another important adaptation before they could leave the water: blinking! Most fish don't blink. But studying mudskippers can tell us more about how blinking evolved. #STEM #sciencetok #SciShow #evolution #biology
