New research helps explain the genetic basis for why we look the way we do
Which genes control the defining features that make us look as we do? And how do they make it happen?

One of the great transformations required for the descendants of fish to become creatures that could walk on land was the replacement of long, elegant fin rays by fingers and toes. In the Aug. 17, 2016 issue of Nature, scientists ...

Hox genes are the master regulators of embryonic development for all animals, including humans, flies and worms. They decide what body parts go where. Not surprisingly, if something goes wrong with these genes, the results ...

Researchers from McGill University have revealed the steps by which two very distinct organisms—bacteria and carpenter ants—have come to depend on one another for survival to become a single complex life form. The study, ...

(Phys.org) —A fundamental question in the evolution of animal body plans, is where did the head come from? In animals with a clear axis of right-left symmetry, the bilaterians, the head is where the brain is, at the anterior ...
If you never understood what "ontogeny recapitulates phylogeny" meant in high school, don't worry: biologists no longer think that an animal's "ontogeny", that is, its embryonic development, replays its entire evolutionary ...
