Phenotypic gradualism

WebFeb 4, 2014 · The phenotypic outcome of the telomere-triggered transposon activity is the saltatory appearance of nonadaptive characters simultaneously in many individuals. Transgenerational telomere erosion is therefore the material basis of aging at the species level. Introduction WebMolecular Evolution.

WebPhyletic gradualism is a hypothesis about the pattern of evolution. In contrast to the theory of punctuated equilibrium, it states the following: • Evolution has a fairly constant rate. • New species arise by the gradual transformation of ancestral species.
