____ analogous structure
____ artificial selection
____ biogeography
____ bottleneck effect
____ charles darwin
____ evolution
____ fossil
____ founder effect
____ gene flow

____ homologous structure
____ natural selection
____ vestigial structure

1. process by which humans modify a species by breeding it

for certain traits.

1. the process by which species adapt over time in response to

their changing environment.

1. body part that is similar in function as a part part of another

organism but is structurally different

1. remnants of an organ or structure that functioned in an

earlier ancestor.

1. evolutionary biology and geography that looks at the

geographic distribution of species over time.

1. genetic drift that occurs after a small number of individuals

colonize a new area

1. a british naturalist who developed the theory of evolution

using the natural selection mechanism.

1. genetic drift that results from an event that drastically

reduces the size of a population.

1. any preserved evidence of life from a past geological age;

impressions and remains.

1. the collection of all the alleles present in a reproducing

population or species.

1. transfer of genes among populations, resulting from the

migration of individuals.

1. change in frequency of an existing gene variant in the

population due to random chance.

1. organisms better adapted to their environment survive, pas

genes, and produce more offspring

1. inherited trait that is selected for over time because it allo

organisms to better survive in their environment.

1. body part that is similar in structure on different organisms

but performs different functions

Explanation:

To solve the matching, we analyze each term:

• Adaptation: Matches 14 (inherited trait for better survival).
• Analogous Structure: Matches 3 (similar function, different structure).
• Artificial Selection: Matches 1 (human - driven breeding for traits).
• Biogeography: Matches 5 (evolutionary biology + geography, species distribution).
• Bottleneck Effect: Matches 8 (genetic drift from drastic population reduction).
• Charles Darwin: Matches 7 (British naturalist, evolution via natural selection).
• Evolution: Matches 2 (species adapt over time to environment).
• Fossil: Matches 9 (preserved past life evidence).
• Founder Effect: Matches 6 (genetic drift from small colonizing group).
• Gene Flow: Matches 11 (gene transfer via migration).
• Gene Pool: Matches 10 (all alleles in a reproducing population).
• Genetic Drift: Matches 12 (gene variant frequency change due to random chance).
• Homologous Structure: Matches 15 (similar structure, different functions).
• Natural Selection: Matches 13 (better - adapted organisms survive/reproduce).
• Vestigial Structure: Matches 4 (remnant of an organ from an ancestor).

Answer:

• Adaptation: 14
• Analogous Structure: 3
• Artificial Selection: 1
• Biogeography: 5
• Bottleneck Effect: 8
• Charles Darwin: 7
• Evolution: 2
• Fossil: 9
• Founder Effect: 6
• Gene Flow: 11
• Gene Pool: 10
• Genetic Drift: 12
• Homologous Structure: 15
• Natural Selection: 13
• Vestigial Structure: 4
