So, another chapter on comparing humans to other animals... I already guessed that humans are related to pretty much every single animal on Earth in some way, but a jellyfish? A sea anemone? 0_0 They do not seem to have anything even close to comparable, but I will just have to accept the fact that we all have the same body plan, just set up by different versions of the same genes.
It was entertaining to read about the gene Noggin and how injecting extra amounts of frog Noggin into a frog egg can transform a frog into a mutant with two heads and extra back structures. That would be cool to see. It is surprising how that one gene can make such a big difference. The Hox genes too, can mess with the body plan of animals significantly. It is interesting how slight changes in the Hox genes can greatly impact the formation of our bodies.
