Vocabulary I
A heritable change in a phenotype that increases the animals chance of successful reproduction.
What is an adaptation?
The theory that detrimental traits for an animal would be eliminated by the failure of the animal to reproduce.
What is natural selection?
The idea that evolutionary changes can occur rapidly over thousands of years and that these periods of rapid change are interrupted by periods of constancy.
What is punctuated equilibrium?
Theory of evolution and natural selection
Who is Charles Darwin?
Changes in gene frequency in a population that result from emmigration/immigration.
What is gene flow?
DAILY DOUBLE:
Changes in gene frequencies that occur when a few individuals from a parent population colonize new habitats.
What is the founder effect?
Large-scale changes that result in the extinction and formation of a new species.
What is macroevolution?
Individuals are prevented from mating, even though they may occupy overlapping regions.
What is reproductive isolation?
Theory of uniformitarianism and the natural forces formed the earth as we know it.
Who are Charles Lyell and James Hutton?
What is comparative anatomy?
The evolution of structures in unrelated organisms.
What is convergent evolution?
The measure of the successful reproduction in a given environment relative to others of the same species.
What is fitness?
The study of the genetic distribution of plants and animals.
What is biogeography?
Studies animal classification, came up with the binomial nomenclature for animals.
Who is Lamarck?
The sum of all alleles for all traits in a sexually reproducing population.
What is the gene pool?
Evolutionary Relationships among species
What is phylogeny?
A change in the frequency of alleles in a populations over time.
What is microevolution?
The study of the genetic events in gene pools.
What is Population Genetics?
Created a mathematical model that shows whether or not evolution is occurring in a population.
Who are Hardy and Weinberg?
A group of populations in which genes are actually or potentially exchanged through multiple generations.
What is a species?
Similar structures from species with a common ancestor.
What are homologous structures?
Descent with modification
What is organic evolution?
Similar structures in unrelated organisms.
What are analogous structures?
Who is Buffon?
Changes in gene frequencies that result when numbers in a population are drastically reduced, and genetic variability is reduced as a result of the population decline.
What is the bottleneck effect?
