the development of new types of organisms from preexisting types of organisms over time

a layer or a series of layers of rock in the ground

the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.

A trait that makes an individual successful in its environment, such as thick fur in cold climates

measure of an individual’s hereditary contribution to the next generation.

the remains or traces of an organism that died long ago

principle states that if the rock strata at a location have not been disturbed, the lowest stratum was formed before the strata above it

age compared to that of other fossils

the study of the locations of organisms around the world

11. Homologous Structure

anatomical structures that occur in different species and that originated by heredity from a structure in the most recent common ancestor of the species

12. Analogous Structure

closely related functions but do not derive from the same ancestral structure

13. Vestigial Structure

seem to serve no function but that resemble structures with functional roles in related organisms

the relationships by ancestry among groups of organisms

15. Convergent Evolution

process by which different species evolve similar traits

16. Divergent Evolution

process in which the descendants of a single ancestor diversify into species that each fit different parts of the environment

17. Adaptive Radiation

when new population in a new environment, such as an island, will undergo divergent evolution until the population fills many parts of the environment

18. Artificial Selection

process occurs when a human breeder chooses individuals that will parent the next generation

when two or more species have evolved adaptations to each other’s influence

Question	Answer
1. Evolution	the development of new types of organisms from preexisting types of organisms over time
2. Strata	a layer or a series of layers of rock in the ground
3. Natural Selection	the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
4. Adaptation	A trait that makes an individual successful in its environment, such as thick fur in cold climates
5. Fitness	measure of an individual’s hereditary contribution to the next generation.
6. Fossil	the remains or traces of an organism that died long ago
7. Superposition	principle states that if the rock strata at a location have not been disturbed, the lowest stratum was formed before the strata above it
8. Relative Age	age compared to that of other fossils
9. Absolute Age	time since formation
10. Biogeography	the study of the locations of organisms around the world
11. Homologous Structure	anatomical structures that occur in different species and that originated by heredity from a structure in the most recent common ancestor of the species
12. Analogous Structure	closely related functions but do not derive from the same ancestral structure
13. Vestigial Structure	seem to serve no function but that resemble structures with functional roles in related organisms
