Biology Unit 4 Assessment 2020-2021 Question: 1-16 cording to the fossil record, giraffes didn't always have long necks. Through time, they evolved to have long necks. What would be the best explanation for the longer necks? 15.13 O Certain traits can be favorably selected through time in a population if members of that population continuously breed with partners with the desired trait; thus, naturally "selecting out" those without the trait O Convergent evolution explains why giraffes have long necks O Divergent evolution explains why giraffes have long necks O The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks

Paleontology

A branch of science concerning the scientific study of life from ancient times is known as paleontology. The scientists working on paleontology are known as paleontologists. Paleontologists collect the fossils of organisms from ancient times to classify them. The paleontologists also study the environment from ancient times to study the interactions between different organisms.
