Which of the following is NOT true of biological evolution?   a. It always involves genetic changes   b. it always involves groups of individuals   c. it requires the existence of genetic variation within a population   d. it can include non-genetic changes in an organism, if the organism is complex enough

What is true about evolution by natural selection? a. It is a largely random process. b. Homology shows that convergence is a useful tool for deducing adaptive function. c. Mothers are invariably members of the same species as their offspring, so selection can never create new species. d. Harmful recessive genes are eliminated more rapidly than harmful dominant genes. e. None of the above is true.

Which of the following is true regarding vestigial traits?   A. Vestigial traits are evidence for change over time   B. Vestigial traits are evidence for common ancestry   C. Vestigial traits indicate that not evolution does not perfect organisms   A and B   A, B, and C

What is the difference between evolution, natural selection, and artificial selection? A. Evolution is a genetic change in a population over time which can occur through natural selection. Artificial selection is the differential reproduction of individuals in a population to promote the characteristics chosen by the breeder.   B. Natural selection is the change of allele frequencies in a population over time.  Evolution leads to differential survival and reproduction of individuals. Artificial selection has produced domesticated animals and plants.   C. Evolution is a mechanism of artificial selection.  Natural selection is a form of artificial selection in which nature selects the characteristics that are most beneficial to a species.   D. Artificial selection is a mechanism of evolution and is the main process of domesticating animals and plants for human use.  Natural selection is the same as evolution.

The definition of "lineage" is:   Select one or more: a.   the same as the Tree of Life   b.   a population of organisms captured at one specific time   c.   a series of ancestor and descendant lineages over time   d.   a character that has evolved over time

A. Genetic drift refers to a. change in the way the body functions as a result of stressors. b. changes in the DNA sequence, particularly in sex cells. c. random changes or accidents that reduce genetic variation in a population. B. All human cultures a. can be correlated with "races" in the past. b. are unchanging and eternal. c. can be ranked as "primitive" or "advanced". d. are integrated and complex. d. exchange of genes when outsiders migrate into an area.

4) Imagine that evolution could be taught using a storyboard. Consider the following "numbered" images below. What story does it tell? 1. 2. 4. 3.

A set of alleles carried by (characteristics of) an organism that encodes for a specific trait. Select one: O a. Genetic diversity b. Karyotype c. Phenotype d. Genotype e. Natural selection

A common and accurate definition of evolution is the change of an individual’s heritable trait. a. False b. True
