Understanding Natural Selection and Giraffe Evolution

What is an adaptation in the context of natural selection?

• A random mutation that occurs in an organism

• A method of organisms migrating to new environments

• A process of organisms becoming extinct

• A trait or behavior that helps an organism survive

Why did giraffes with shorter necks struggle to survive?

• They had difficulty finding mates

• They were more prone to diseases

• They could not reach food high in the trees

• They were unable to run fast enough from predators

What was the main reason for the decline of short-necked giraffes?

• They were hunted by humans

• They could not compete for food with long-necked giraffes

• They migrated to less favorable environments

• They were affected by climate change

How did long-necked giraffes become more common over time?

• They passed on their long neck trait to their offspring

• They adapted to colder climates

• They developed a new diet

• They were selectively bred by humans

What does the story of the giraffe's neck illustrate about natural selection?

• It demonstrates how environmental changes can lead to new species

• It highlights the importance of genetic diversity

• It illustrates how advantageous traits are passed on to future generations

• It shows that all species eventually become extinct
