Evolution Flashcards
Adaptation
Inherited characteristics that increases an organisms chance of survival
Evolution
Change in a kind of organism over time
Adaptive radiation
A single gene species or small group of species evolves into several different forms that live in different ways
Allele frequency
the percentage of all alleles at a given locus in a population gene pool
Artificial selection
Selection by humans for breeding of useful traits from the natural variation among different organisms
Embryology
noun
1.
the branch of biology and medicine concerned with the study of embryos and their development.
Fitness
Ability of am organism to survive and reproduce in its environment
Fossil
Preserved remains of an organism
Founder effect
Change in allele frequencies as a result of migration of a small subgroup of a pop
Gene pool
Combined genetic information of all the members of a particular pop
Genetic drift
Random change in allele frequencies that occurs in small pops
Genetic mutation
Changes in the genetic material
Homologous structures
Structures that have different mature forms in different organisms but develop from the same embryonic tissue
Macroevolution

Microevolution
1.
evolutionary change within a species or small group of organisms, esp. over a short period.
