Darwin was the first to explain

A correct mechanism for evolution

How to record observations

The quick rate of evolution

A theory of inheritance

Evidence that supports the theory of evolution includes all of the following EXCEPT

the fossil record

Ratios of males to females

Comparing anatomical structures

molecular data

A human arm and a bat wing are each made up of a similar number and arrangement of bones. This similarity is evidence that humans and bats

Have an ancestor in common

Have the same parents

Evolved at the same time

once shared the same habitat

The sum of allele frequencies in a population should be

Equal to the phenotype frequencies

One-half of the genotype frequencies

Equal to 1

less than 100

Population genetics is the study of

How populations interact

How genes determine traits

How individuals evolve

How alleles change within populations

A species is generally defined as a group of natural populations that can

Have the same range

Share resources

Interbreed

Inhabit the same environment

After studying plant and animal life in South America and the Galapagos Islands, Darwin proposed that

Galapagos species and South American species were unrelated

Galapagos species had descended from South American species

Galapagos species and South American species had descended from European species

South American species had descended from Galapagos species

Comparing fossils and living beings reveals

That the earth is very young

That ancient organisms are no different than organisms today

A pattern of gradual change from past to present

That ancient organisms were all very small
