how many theory's of evolution are there?

Question

like biological, mutaion or somthing,.

Answer 1

There is really only one theory. The core principles are that mutations create diversity in a population, and natural selection makes certain individuals have more descendants than others, based on how well they exploit their environment. For example, bacteria mutate rapidly, and as humans use more antibiotics, the ones that carry antibiotic-resistance mutations survive and thrive, while the others die out.

The theory can become more complex when applied to certain situations -- for example, when species that are in competition co-evolve, or when evolution is driven by success in attracting mates. But the basic ideas are the same.

Answer 2

Try reading some overview work on the subject. Most of Darwin's work covers microevolution. The basic principle is survival of the fittest. Genetic variations (mutations) which offered a competitive advantage in survival or mating tend to persevere. Those which do not, tend to become disused and fade away. There is nearly universal agreement that this is scientifically accurate. Macroevolution takes the same scientific evidence and observations but makes much broader claims about the origin of life and of individual species. Proponents of some of these ideas go far beyond what science supports. If you counted all the variants, you'd end up in the thousands to the tens of thousands.

Answer 3

Decades before Darwin, many biologists concluded that modern species were the result of an evolutionary process, including Darwin's grandfather, Erasmus Darwin. The first biologist to publish extensively on evolution was Jean Baptiste de Lamarck. Lamarck's ideas spoke to three issues of evolution: fact, course and mechanism. Because of the lack of understanding of heredity by genes, Lamarck proposed that an organisms attempts to adapt to an environment led to heritable changes. Unfortunately, despite all of his seminal contributions, this error is what he is most remembered for. It was Darwin, who first proposed the idea of evolution by means of natural selection. This has become the theoretical paradigm of all modern biological science. Such evolutionary processes as endosymbiosis, genetic drift, punctuated evolution, etc., are not competing theories of evolution per se, but just aspects of how evolution by natural selection works under some conditions.

Answer 4

There is one general Theory of Evolution and it covers the general principles on the subject. The total number of all theories would equal the number of scientists who study in the field, because they all have a viewpoint on the details.

Answer 5

to many but i think there are 5 or 6

Answer 6

Two, the religious viewpoint and the right one.

Answer 7

Too many as far as I am concerned.

Answer 8

One is to many.
