Evolution: Rates Of Evolutionary Change

Rates of Evolution
Rates of evolution change vary widely over time, among characteristics, and among species. Evolutionary change can be estimated by examining fossils and species that are related to each other. The of change is governed by the life span of the species under examination, short-lived species are capable of changing more quickly than those that have a longer life span and reproduce less often. Yet, even short-lived species such as bacteria, which have generation times measured in minutes, do not manifest noticeable evolutionary changes in a humans lifetime. Basic techniquine
One technique that has been used to examine the rate of evolutionary change is DNA analysis. This technology involves identifying the percentage of
