Question

PLEASE HELP ASAP!! NEED THIS DONE FAST.. 35 POINTS. Darwin explored the Galapagos Islands and observed variations of certain species. For example, he saw that the mockingbirds on three different islands were distinct, but still similar to the mockingbirds found on the mainland. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction. If the mockingbirds became extinct, explain how the newly available niches could lead to speciation.

Answer 1

Answer:

The different genes that were expressed gave a advantage and disadvantage to certain finches. The ones least capable of surviving with their traits became extinct over time, and the other ones survived, bringing numerous new traits and advantages to the finches, changing them completely. Sometimes, finches can mate with other finches, giving them different traits and survival advantages and disadvantages.

Answer 2

Speciation is the process of creating new species of plants or animals from the old ones. The newly available mockingbird is the result of breeding of the mockingbird to other species on another island, which creates new species.

What is speciation?

Speciation is when a new species of plant or animal creates within the old species. Speciation occurs when an organism of a species goes to another place to live and create different characters and when this species breed with old species a new species develops.

Thus, the newly available mockingbird was produced by mating the original mockingbird with another species on a different island, which results in the creation of new species.
