In forming his theory of evolution, Darwin most lacked an adequate understanding of

An inherited trait that helps an individual survive and reproduce in a particular environment is
an adaptation.
a survival trait.
a genetic trait.
natural variation.
A human arm and a bat wing are each made up of similar number and arrangement of bones. This similarity is evidence that humans and bats
evolved at the same time.
have the same parents.
have an ancestor in common.
once shared the same habitat.

Darwin's laws of heredity.
Darwin's theory of natural selection.
Darwin's idea that species evolve gradually.
Darwin's predictions of intermediate forms.
