'24 Biological Evolution Test DRAFT

What is a homologous structure?

• having a body part that has no known function
• similar structures in more than one organism because they evolved from a common ancestor
• similar structures that evolved independently in two living organisms to serve the same purpose
• a structure that evolved to help an organism survive in their environment

Whales live in the ocean. They do not have legs, but they do have a pelvis with small leg bones attached to it. This is evidence that:

• Whales are not well adapted to ocean life.
• Whales do not have homologous structures
• Whales evolved from animals that once lived on land
• Whales evolved from some type of fish

What is true about the embryology of vertebrate organisms?

• Embryos look the same as the adult organism
• Haeckel's drawing were completely accurate and detailed
• Embryos do not change much during development
• The more closely related two organisms are, the closer their embryology will be.

What evidence do similarities between fossil bones and modern organisms provide?

• species that face similar environmental pressure will develop similar traits.
• homologous structures are evidence that the two species are related or shared a common ancestor
• natural selection
• adaptive structures help organisms survive in their habitat

Human beings are taller than they used to be. Over the last 150 years, humans have on average increased in height of about 10 centimeters. What principle does this provide evidence for?

• species change over time
• extinction occurs when the species cannot adapt to rapid change in environmental pressures
• homologous structures
• camouflage is an adaptive change

The golden eagle has very strong eyesight. Their eyesight is about 8 times stronger than that of the average human. They can see a mouse about 2 miles away! This probably helps them with hunting. What type of structure would the golden eagle's eyes be?

• adaptive structure
• analogous structure
• vestigial structure
