[What Darwin Never Knew]

I was surprising while I watched the document video. it was really great video. I didn’t have interesting biodiversity before I watched the video. now, I interesting in Adaptive Radiation of Darwin’s Finches

I learned any animals and human look different by envelopment. get be used where he or she lives also if they’re born same parent first time, they look similar but it will be changed if they grew different area. however I want to know more about behavior or inherited[acquired] character because they effected to change appearance by envelopment. How about character or personality?

I found a picture on google site. it is Adaptive radiation in Galapagos finches. it is really interesting to me

Fourteen species of Galapagos finches that evolved from a common ancestor. The different shapes of their bills, suited to different diets and habitats, show the process of adaptive radiation.

The finches of the Galapagos Islands provide a classic example of adaptive radiation—the evolutionary process through which a single lineage gives rise to species occupying diverse environmental niches. In one model of how species form, geographical separation leads to evolutionary divergence. Recent evidence permits refinement of this model. For one thing, the relationships among Darwin’s finches have become clearer through studies of DNA sequence variation. Also, it is now clear that the Galapagos Islands have changed radically over the 3 million years during which the finches have evolved; changes in the character of the archipelago have helped drive the radiation of species. The birds? physical appearance and song appear to act as cues that help isolate populations when mating. Though it is not yet possible to thoroughly recount how Darwin’s finches have evolved, an increasingly dynamic view of adaptation offers an improved explanation.

  1. Awesome post!

    I like the diagram you put up there. It is really cool to see by comparison how different each beak has become over the millennia, from thin and snappy insect snatchers to thick and hardy seed crackers (who doesn’t like seed crackers?).

    You mentioned how, “It is not yet possible to thoroughly recount how Darwin’s species have evolved.” I see this as a cool opportunity. Are you in Computer Animation? Wouldn’t it be great to make animations for National Geographic of the evolution of species over time? I bet Nat Geo would love this. They could even make a separate site where you could view the 3D models change over time on a pedestal of some sort, turnaround style.
