Document Summary

Evolution is the change in the genetic composition of populations over time. The evolutionary theory is applied to study many different things like treatments of diseases and agriculture practice: the definition: the understanding and application of the mechanisms of evolutionary change to biological problems. European species: this led him to ask why there is a difference between the species in relation to geography. Species are not immutable, they change over time. Divergent species share a common ancestor and have diverged from each other: this is called descent w modification. A population is a group of individuals of a single species that live and interbreed in a particular geographic area at the same time. Mutations cause different forms of a gene (alleles) to exist at a particular chromosomal locus. Natural selection can increase the frequency of beneficial mutations in populations. A favored trait that evolves through natural selection is known as an adaptation.

QUESTION 5

Darwin's concept of evolution "the theory of descent withmodification through variation and natural selection" can bedemonstrated by which of the following examples?

		A giraffe stretches his neck to reach higher branches. Theexercise of stretching up strengthens the muscles in the neck andlegs. This ability to stretch is also seen in the giraffe'soffspring.
		A monkey accidently drops her fruit in the salty water of a bay,she recovers the fruit and eats it. She discovers that the fruit iscleaner and tastes better after it has been in the salty water. Shecontinues to wash fruit in the bay before eating. Her offspring seewhat she has done and also wash their fruit in the salty water.Soon the whole population is washing their fruit
		Several turtles hatch from a clutch of eggs buried in the sandon a beach. One of the turtles is the color of the sand, the othersare darker in color. The turtles all scurry to the water, but oneby one the dark turtles are eaten by birds, only the sand coloredturtle survives. When it enters the water the sand color changes toa darker brown. The turtle grows, mates and has offspring that arealso sand colored when they are born
		A female alligator gives birth to a male alligator that has theability to change color to a bright white when it is in cold water.The baby male alligator is quickly spotted by a large bird of preyand eaten

QUESTION 6

During the Beagle journey, Darwin visited islands,allowing him to compare island species with continental species. Interms of framing his theory of evolution, why was thissignificant?

		Because the island species had both similarities to theircontinental ancestors and unique adaptations to their islandenvironments
		Because the island species no longer shared traits with theircontinental ancestors
		Because the species he saw on the islands had not changed fromtheir ancestral continental form
		Because the island species had very low reproductive andsurvival rates as compared with their continental ancestors
