Define Evolution.
Change over time; the process by which
modern organisms have descended from ancient organisms.
Only individuals with a desired trait, such as color, are bred by humans in the hope that the next generation will inherit that desired trait is known as…
Artificial selection.
What is fossil record?
Fossil record is something that scientists use to interpret and comprehend.
What are proteins?
Proteins are complicated molecules that carry out important cell materials.
Name the 3 organisms that Darwin observed in the Galápagos Islands.
Armadillos, Finches, and mocking bird.
Define artificial selection.
The process by which humans breed only those organisms with desired traits to produce the next generation.
What is sexual selection?
Sexual selection is the measure of an individuals fitness is its ability to survive and reproduc.
How do fossils form?
Fossils form by leaving a impression on the stone after a organism has perished and got covered by a material.
