The nationwide experiment will initially include around 100,000 volunteers.
Developmental biologists take a close look at how alligator embryos grow.
January 8, 2018|
JOÃO FRANCISCO BOTELHO, YALE UNIVERSITY Alligator embryos share many characteristics with bird embryos, a hallmark of their shared evolutionary heritage. Their last common ancestor lived some 250 million years ago, and would have resembled a small dinosaur. Evolutionary biologists are comparing the development of chicken and alligator embryos to pinpoint stages where bird and crocodylian features emerge.
