Scientists found that fruit fly embryos can develop through multiple genetic paths, not just one. This challenges traditional ideas.

Since then, however, many investigators have unearthed molecular evidence that the genes involved in odontogenesis (tooth development) are indeed retained in chickens. A primary step in reaching ...

No one would ever confuse a human being with a mouse, a chicken, or an elephant, but at the very start of their different ...

So, Haeckel proposed, by examining the development of an embryo you could read its entire evolutionary history in the transition from one stage to another. In fact, this isn't strictly true ...

Old viral DNA, once thought to be gone forever, is reactivated in mammalian embryos, with each species showing unique ...

Ancient viruses are embedded everywhere in the human genome. It's thought that about 8% of the human genome... | Genetics And Genomics ...

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.
