Bio >>:C Flashcards
the evolutionary process whereby an organism becomes better able to live in its habitat or habitats
Adaptation
Similar physical features in organisms but serve completely different functions
Homologous structures
similarity of function of structures that have different origins
Analogous Structures
Genes that specify segment identity
Hox Gene
Cytochrome C???
Cytochrome C
The study of the distribution of species and ecosystems in geographic space and through time
Biogeography
Process by which organisms best adapted to their environment survive to pass their genes on through offspring
Natural Selection
An evolutionary tree that shows the ancestral relationships among organisms
Cladogram
The study of the development of an embryo
Embryology
Genetic variability drifts out of a population
Genetic Drift
Bottle neck effect
Founders effect
examples of:
Genetic Drift
Genetic variety flows into a population
Gene Flow
Combination of all the genes present in reproducing population or species
Gene Pool
Isolation
Just a vocab word
The idea that evolution occurs in spurts instead of following the slow, but steady path
Punctuated Equilibrium
