evolution

allopatric a mode of speciation, through which one group of a population breaks away from another, becomes geographically isolated, and changes gradu­ally over time due to differences in environmental pressures.

biased gene conversion unrelated to natural selec­tion, a process that speeds up the rate of evolution in certain genes, through both positive and negative mutations, which may spread rapidly throughout a population.

catastrophism theory of evolutionary change brought about by a worldwide catastrophe, such as a collision with an asteroid and resulting climate change.

cladistics the classification of species according to evolutionary lineage. Also known as phylogenetics.

cladogram a diagram showing the branching off of life-forms as they evolved into different forms. Also called a family tree or tree of life.

classification in modern biology, a hierarchical arrangement of life-forms in related groupings, specif­ically by species, genus, family, order, class, phylum, and kingdom.

coevolution the ongoing adaptation of two or more animals in the same geographical range, through which changes in one lead to changes in the other, as predator and prey.

common ancestor the forebear from which two different species branched off and evolved their own traits.

convergence the independent development of the same useful trait in two or more different species, as wings are convergent in birds and bats.

creationism a religious explanation for all of Earth's diversity, through which an all-powerful god created all life-forms in their present state, a belief system

derived from the Bible and discredited by mainstream science.

Darwinism Charles Darwin's scientific theory that life continuously evolves and species change over time due to environmental pressures and natural selection.
