An interesting article about
amphioxus, a marine invertebrate, leads to fascinating ideas about evolution in general and human evolution in particular.
Click here for more The human genome has only about 25 percent more genes than the amphioxus genome, according to Holland. During evolution, humans have duplicated genes for different functions. Such duplication has given humans and other vertebrates a much larger “toolkit” for making various structures that are absent in amphioxus, including cells for pigment and collagen type II-based cartilage, for example.
I'll be glad to read the comments of experts on evolutionary processes...
