The wings of birds and the wings of bats are examples of:

• vestigial structures

• homologous structures

Vestigial structures are:

• features in different species that share a similar basic structure due to common ancestry, but may have different functions

• features in different species that have similar functions but evolved independently, meaning they don't share a common ancestor

• body parts or behaviors that were once functional in ancestors but have been reduced or lost their original function in modern organisms

Which scientist proposed the idea of inheritance of acquired traits?

• Lamarck

• Darwin

• Mendel

• Watson

What is the primary source of genetic variation in a population?

• natural selection

• genetic drift

• mutation

• migration

NGSS.HS-LS3-2

the change in the frequency of a gene variant (allele) in a population over time due to chance events, not natural selection (like bottleneck effect and founders effect)

• gene pool

• genetic drift

• natural selection

• gene flow

the sum of all the genes in a population of a given species

• gene pool

• gene flow

• population

• genetic drift
