Evolution Ch 1 terms

1. Biological evolution ____

2. Fossil ____

3. Genetic drift ____

4. Homologous ____

5. Lineage ____

6. Mutation ____

7. Natural selection ____

8. Phenotype ____

9. Morphology ____

10. Phylogeny ____

11. Genus ____

12. Synapomorphy ____

13. Viral reassortment ____

A. Occurs when genetic material from different strains is mixed into new combinations within a single cell

B. A mechanism that can lead to evolution, whereby differential survival and reproduction of individuals cause some genetic types to replace (outcompete) others

C. Any change in the inherited traits of a population that occurs from one generation to the next (that is, over a time period longer than the lifetime of an individual in the population)

D. Any change to the genomic sequence of an organism

E. Describing a characteristic that is similar in two or more species because it is inherited from a common ancestor

F. Evolution arising from random changes in the genetic composition of a population from one generation to the next

G. A chain of ancestors and their descendants. It may be the successive generations of organisms in a single population, the members of an entire species during an interval of geological time, or a group of related species descending from a common ancestor.

H. A visual representation of the evolutionary history of populations, genes, or species

I. A derived form of a trait that is shared by a group of related species (that is, one that evolved in the immediate common ancestor of the group and was inherited by all its descendants)

J. A measurable aspect of organisms, such as morphology (structure), physiology, and behavior.

K. Preserved evidence of life from a past geological age, including impressions and mineralized remains of organisms embedded in rocks

L. Referring to the form and structure of organisms

M. Taxonomic group that includes species
