As they grow, the differences that will distinguish the embryos as adults become more and more apparent. The study of this development can yield insights into the process of evolution.

For example, in 1821, Geoffrey St. Hilaire was the first scientist to publish the observation that some bird embryos exhibited evidence of ... to demonstrating the evolution of gene control ...

But Clarence Darrow and the ACLU had succeeded in publicizing scientific evidence for evolution, and the press reported that though Bryan had won the case, he had lost the argument. The verdict ...

In a new discovery, scientists have found evidence that could ... that the genetic programming for embryo formation may have existed long before the evolution of complex multicellular organisms.
