Which of the following ideas was NOT part of Darwin's contribution to science?

Darwin first began to formulate his concept of evolution by natural selection after

Charles Darwin called the ability of an organism to survive and reproduce in its specific environment

According to Darwin's theory of natural selection, individuals who survive are the ones best adapted for their environment. Their survival is due to the

Anatomical structures that have similar bone structure but do not have similar functions are called:

Natural selection acts directly on

If a mutation introduces a new skin color in a lizard population, which factor might determine whether the frequency of the new allele will increase?

Species Y and Z have very similar proteins, genes and genetic sequences. What is most likely true about these two species? Species Y

Anatomical structures that have similar functions but do not have similar structures are called:

The process by which one species significantly influences the evolution of another species is called:

Change in a population over a period of time is known as

Whenever two populations try to occupy the same niche(habitat)

Which is NOT part of the theory of natural selection?

Evolution that produces similar characteristics in unrelated species is

During Darwin's visit to the Galapagos Islands, what did he observe about finches?

Which term describes structures similar in purpose but not inherited from common ancestors?

Which structure does NOT link species together with a common ancestor?

Evolution is caused

Natural selection causes

The human arm, the whale fin, and the bat wing are traits that may have evolved from a common ancestor. They are

The theory of evolution predicts that

The evolution of one or more species from a single ancestor species is

Strong evidence for evolution comes from

Structures that are present in an organism but are reduced in size and have little or no function are called

34. The characteristics of the individuals best suited to a particular environment tend to

Darwin conducted most of his research

If mates, shelter, food become limited competition decreases.

Which gas was NOT available in early Earth?

The theory of Endosymbiosis explains

___________ & _________________ are organelles that definitely arose from endosymbiosis.

Evolution is a very rapid process, taking only 1-2 generations for a species to fully change.

What is a half life?

The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed?

After the third half-life, how much of the sample is left?
