Describe how finches of the Galapagos Islands adapted over time.

Biology

konstantin123 [22]2 years ago

Answer:

Darwin observed the Galapagos finches had a graded series of beak sizes and shapes and predicted these species were modified from one original mainland species.

Darwin called differences among species natural selection, which is caused by the inheritance of traits, competition between individuals, and the variation of traits.

Offspring with inherited characteristics that allow them to best compete will survive and have more offspring than those individuals with variations that are less able to compete.

Large-billed finches feed more efficiently on large, hard seeds, whereas smaller billed finches feed more efficiently on small, soft seeds.

When small, soft seeds become rare, large-billed finches will survive better, and there will be more larger-billed birds in the following generation; when large, hard seeds become rare, the opposite will occur.

Describe the difference between selective breeding and genetic modification
tekilochka [14]

Individuals in selective breeding should be of the similar species. Scientists use GMO to generate new gene combinations. Genes pair on their own through selective breeding.

<h3>What is genetic modification?</h3>

A technique to change the characteristics of a plant, animal, or microorganism by swapping a piece of DNA from one organism to an another organism is referred to as gene modification.

Selective breeding entails selecting parents with specific characteristics to breed with in order to generate offspring with more desirable characteristics.

Individuals in selective breeding should be of a similar species. Scientists use GMOs to generate new gene combinations. Genes pair on their own through selective breeding.

Thus, this is the difference between selective breeding and genetic modification.
