Lemurs are primates found only on the island of Madagascar off the east coast of Africa. The common ancestor of lemurs and bush babies lived in Africa 62 million years ago. Which statement most likely explains how the ancestors of lemurs arrived in Madagascar?

• Lemur ancestors traveled to Madagascar from Africa.

• Humans moved lemurs to Madagascar millions of years ago.

• Lemurs existed in Madagascar before the African common ancestor.

Some humans have the ability to wiggle their ears.

Scientists believe this is because our ancestors used these muscles to move their ears to locate the source of sounds.

Today, humans turn their heads instead to locate sounds.

Which word best describes the muscles that wiggle human ears?

• homologous structure

• analogous structure

• vestigial structure

The modern-day fox and dog share a wolf-like common ancestor. For this reason, they share many characteristics including:

ears that can move toward sounds

fur coats that keep them warm

sensitive noses that help them to find prey

Which word best describes how the shared structures in the fox and dog evolved.

• analogous structures

• divergent evolution

• convergent evolution

Which is not evidence for evolution?

• many animals have homologous structures due to common ancestry

• Many animals have vestigial structures from an ancestor

• We can observe changes in life forms by observing the fossil record

• All of these are evidence for evolution

The study of the early stages of development that is one evidence of evolution is:

• Homologous Structures

• Embryology

• Vestigial Organs

How does embryology support the Theory of Evolution?

• It shows that they have a common ancestor because of their similarities.

•          I'm not sure.

• Animals change over time.

Structures are similar in function but not in anatomical structure
EXAMPLE: bird wings vs. butterfly wings

• Vestigial

• Homologous

• Analogous Structures

• Embryonic

Which sentence best describes why rat and thrasher tails have a similar function?

• Rats grew tails on purpose to imitate thrashers.

• The animals live in similar environments, so convergent evolution led to similar adaptations.

• The common ancestor of thrashers traveled to where rats live.
