As discussed in Module 2‚ the beaks of the Galapagos finches changed during the 1976-1977 drought; they became deeper (stouter). A. Draw a simple frequency distribution (a bell curve) of finch beak depth before the drought. (Google “graph of frequency distribution” if you don’t know what one looks like

He provided mass amounts of evidence after traveling to the Galapagos Islands for research to support his ideas and eventually‚ his fundamental proposals would forever change the world of science‚ anthropology‚ philosophy‚ and faith. To begin‚ Darwin tells us that every species (within populations) contains variation;

types of plants. To make sense of these types of ecological patterns we require a phylogenetic (historical) perspective: we need to focus on monophyletic groups. The importance of a geographic scale was certainly appreciated by Darwin: the Galapagos finches were morphologically distinct and geographically distinct and there must be a connection. Moreover‚ the general view that speciation is a central phenomenon in evolution‚ and that most speciation is allopatric speciation assumes that geography

Vonnegut’s Galapagos 1) Does Vonnegut’s fictional account reinforce or alter your current understanding of Darwin’s evolution theory? Are there any surprises here? Is there anything about evolution theory that perhaps had not occurred to you? Vonnegut’s Galapagos reinforced by current understanding of Darwin’s evolution theory through a fun narrative I could understand. As I read this Darwinian tale of survival‚ I watched humans just like you and me devolve from "big brained" organisms

the Pacific Coast of South America. When he called at the Galápagos Island‚ he realized that even though in the same species‚ they changed their figure according to their environment for a long time. Moreover‚ Charles Darwin supposed that all creatures were a natural part of the evolutionary process. Galápagos iguana is a good example of this supposition. There are three types of iguanas‚ namely land‚ marine and black and white in the Galápagos Island. Now I would like to mention two differences and

The Galapagos are a part of the Ecuador. It’s a home to vast array of plants and animals. This area is not only rich with diversity but a place to be vigilantly protected. It was by the year 1835 when Charles Darwin made his discoveries about the species that were thought before to be immutable to be now part of
