Issues of Tempo and Mode in Evolution

There are many ways to explain how the earth and everything is formed. For example, change theory, catastrophe, gradualism, discontinuity equilibrium, etc. In general, homogenization and catastrophe are grouped, but the intermittent equilibrium and the stepism are separated from homogenization and catastrophe. Gradualism and intermittent balance is usually seen through the Bible's position, not from the perspective of the opposite of change and disaster theory.

Evolutionary biology is based in part on paleontology which answers questions about evolutionary patterns and rhythms using fossil records and is based in part on the development of fields such as population genetics. In the 1980's, developmental biology was re-entered into evolutionary biology through research on evolutionary developmental biology. Phylogeny, phylogeny and taxonomy are related fields and are often considered part of evolutionary biology. Phylogenetic trees of all living organisms based on rRNA gene data, indicating separation of the three domain bacteria, archaea and eukaryotes first described by Carl Roese. Although trees constructed with other genes are usually similar, they may arrange some early branches very differently, perhaps due to rapid rRNA evolution. The exact relationship between these three fields is still under debate

Evolution occurs in two main modes. For the first time, with physical transformation, the entire population has changed from one state to another. If all evolutionary changes occur in this pattern, life will not last long. Racial evolution does not increase diversity, it just changes one thing to another. The extinction (not due to evolution to others, but due to extinction) is so common that the biota which does not increase the diversity mechanism will soon disappear. The second model, complementing the earth complements the Earth. Continuous parents from new branches

Mcfadden, B. Phylogenetic pattern of fossil horses and speed of evolution: Camelids of the Miocene and Pliocene of North America. Paleontology 1 (3): 245-257. (Analysis of the evolution of river species, the pattern of seed formation is evident since six of the 16 known species emerge suddenly. Of the ten species that gradually emerge to determine the pattern of seed formation There are five species, which are speciation (conversion from ancestral to progeny, which causes "anesthetic" disappearance ") and 5 (to separate new species from splitting ancestral species, to keep two species coexisting ).
