Convergent evolution is independent evolution of different species that forms similar features. This can commonly be mistaken for divergent evolution, which is when related species form different features which causes them to split into two species. An example discussed in "Improbable Destinies" chapter 1 was how marsupials and mammals are evolutionary distinct but have multiple counterparts that look similar. I chose to depict the sugar glider and flying monkey in my depiction but the chapter also discussed marsupial mole-mole, wombat-groundhog, quoll-wildcat, and thylacine-wolf. These animals look identical to one another but one is placenta bearing and one has an external pouch. This convergent evolution could possibly come from the fact that geologically the pouch bearing animals tend to have shorter gestation periods or that they are not able to provide enough nutrition to the growing marsupial without it being outside of the womb. Since mammals have longer gestation p...
First, I really love the way you are incorporating your final project into your post; I think they newspaper is a great idea! It really provided a great way to explain your definitions and the image that you choose. My only comment would be that a more in-depth visual would really add to your post!
ReplyDeleteYou really went in depth with explaining the different species concepts and the advantages and limitations of each one. I would agree with Maddie regarding the visual, as I think that would really help elevate your final project!
ReplyDeleteWow! This is super in depth. Everything is very clear and easy to follow and your explanations are very informative. I think the clear points for each concept at the beginning really helped provide a base understanding. Awesome job!!
ReplyDeleteI appreciate the depth you went into for each of your concepts of species, your final project is looking to be very interesting! I think that each of the concepts have their merits; it's going to take a lot of debate before we finally come up with a definition that's universally applicable, if that's even possible.
