https://en.wikipedia.org/wiki/Character_displacement 1.)This page has plenty of room for growth. Applying research that has been conducted on character displacement in relation to the galapagos finches could allow there to be a better understanding on the evolution of the Galapagos finches. This could be done by looking at the Geospiza fortis who diverged in beak size from Geospiza magnivostris 22 years after its arrival to the island.

https://en.wikipedia.org/wiki/Darwin%27s_finches 1.)I very much enjoyed the portion of Molecular basis of beak evolution, I think it would be great to have even more information on the beak evolution of the finches. Adding another subtopic such as the morphology of the beaks could help broaden the knowledge of evolution in finches. Discussing environment and describing the impact it had on finches beak size would be a way to approach the topic. There is on going research describing species such as the Geospiza fortis and the Geospiza scandens that describe these changes.

2.)Adding on to the topic of beak size among the finches there could be a portion that shows factors that have contributed to the change and evolution of finches beak size, for example character displacement.


Character displacement has indicated to be a major factor in beak size among finches located on the Galapagos Island and Hawaii.(Shluter 1988)
