The process by which species arise and change.

Which of the following misconceptions about evolution can be refuted with the molecular evidence that is being collected through DNA analysis?

This is the study of fossils

Human-controlled breeding to increase the frequency of desired traits

The remains and traces of past life or any direct evidence of past life.

Layers of sediment

An evolved trait that helps an organism be more suited to its environment

The theory of __________ proposed that a series of catastrophes or mass extinctions followed by repopulation could explain why species change over time.

During the course of Darwin's journey aboard the H.M.S. Beagle he was collecting and recording ________ and __________.

What viewpoint was proposed by Aristotle about living organisms?

An idea that could be traced back to Plato is that

Darwin's observation that there were Patagonian hares but no rabbits in South America would be considered ______________ evidence.

A line of evidence NOT considered by Darwin in his development of the theory of natural selection is

Field of biology that studies the diversity of populations at the gene level.

Term used to describe organisms that are incapable of interbreeding.

Evolutionary changes that occur within populations

A higher-ranking animal has greater access to resources than does a lower-ranking animal.

Term for when males and females differ in size and other traits.

This is founded when two or more extreme phenotypes are favored over the intermediate phenotypes.

The most common source of genetic variation in sexually reproducing organisms is

Which of these conditions is NOT among the requirements of the Hardy-Weinberg equilibrium of allele frequencies in a population?

Mutations that result in resistance to specific antibiotics in bacterial organisms occur

Variations within a population are maintained by

If two adjacent populations of the same species show gene flow, then the two populations will

Which statement is NOT true about the Founder Effect?

Which statement is NOT true about natural selection?

The recessive allele for sickle cell anemia is more prevalent in regions of Africa where malaria is prevalent, than it is in regions where there is no malaria. This is due to a

What is the most plausible explanation for why the male of most bird species have elaborate plumage and mating rituals?

The splitting of species into two or more species.

Term for the physiological behavioral and genetic process that inhibit interbreeding

This is the eventual result of populations that have become separated by a geographic or other type of physical barrier.

This occurs when a biological trait evolves in two unrelated species as a result of exposure to similar environments.

This occurs when 2 different but related species of plants hybridize. Hybridization is then followed by a doubling of chromosomes.

Term used to describe traits that are similar because they evolved from a common ancestor.

This relies on identification of certain morphological traits to distinguish one species from another; it was proposed to explain speciation in the fossil record; members of a species must share a distinct and evolutionary pathway.

The morphological species concept involves the identification of certain structural traits, called _______, to distinguish one species from another.

All of the following statements concerning the evolutionary species concept are true EXCEPT

The biological species concept is limited, and may not be applied to

A _____ is the first cell that results when an egg is fertilized by a sperm.

Isolating mechanisms that prevent reproductive attempts or make it unlikely that reproductive attempts will be successful are referred to as

In some plants, the sperm can not reach the egg because the stigma prevents formation of the pollen tubes. This is an example of

Norway rats (Rattus norvegicus) and roof rats (Rattus rattus) are different species. Occasionally, mating occurs if the two species are kept together in captivity. The resulting pregnancies are not successful and the embryos die. This is an example of

Female Anolis distinguish males of their species by the color of their dewlap, a colorful flap of skin in the neck region preventing them from mating with males of different species. This is an example of

Term for origin of life from nonliving matter

These are formed from proteinoids when they are placed in water; they are structures composed only of protein that have many properties of a cell.

These are formed from micelles; they are large and are surrounded by a bilayer of fatty acids.

The study of the fossil record that results in knowledge about the history of life.

Fossils that identify deposits made at apparently the same time in different parts of the world.

This is produced by cyanobacteria that helps block uv radiation
