Evolution Practice (GH)

Change over time is 

• evolution
• natural selection
• variation
• fitness

Fitness is defined as 

• adaptations to the environment
• the ability to survive
• the ability to reproduce
• the ability to survive and reproduce

Structures that are the present (although not identical) in two different species that came from the same ancestor are called

• analogous structures
• vestigial structures
• vital limbs
• homologous structures

The closest relation to humans are

• frogs
• gorillas
• pigs
• horses

The oldest fossils will be found in which layers?

• Beach sand
• Top of a mountain
• Bottom of a canyon
• By waterfalls

Structures that are inherited from a common ancestor are homologous.

• True
• False

Humans, birds, whales, and lizards all have similar arm bones. What is the reason for this?

• The function of these bones is the same in all animals
• They live in similar environments
• They have a common ancestor
• All organisms resemble humans
