Q:

What is organic evolution?

A:

Organic evolution are the events involved in the evolutionary development of a species. It means that all life descended from other life, although features may have changed dramatically along the way.

Organic evolution involves modifications to existing species, not the development of new ones. Charles Darwin came up with an explanation of evolution known today as Darwinism. Darwinism explains an organism's struggle to exist as well as survival of the fittest and acquired characteristics. J.B. Lamarck believed organic evolution happened because future generations inherited specific characteristics and his theories came before Darwinism.

Examples of organic evolution include organs that are different in structure, but perform similar functions. A dolphin's flippers and a human's arms are examples of organic evolution. Biogeography suggests that certain species developed characteristics to help them survive in different parts of the world. One creature's hands, for example, may only be suitable to the area in which that creature lives and would be useless in another area of the world. Divergence is the process in which organisms develop new, unique traits unknown to their ancestors.

Part of evolution involves the mutation theory. The mutation theory suggest that mutations in genes can be found in all living organisms. Darwinism combined with the mutation theory form Neo-Darwinism, the modern theory of evolution.

  • Q:

    How does natural selection lead to evolution?

    A:

    Natural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve. If a group of people have predominantly brown hair genes and have children, then by way of natural selection the dominant gene will increase with future generations, meaning that slowly in time this group of people will evolve to have mostly brown hair genes.

  • Q:

    Is evolution false?

    A:

    Though scientists argue about the details of how evolution occurs and the types of evolution, they almost universally agree that evolution is true. The fossil record, homologies and scientific experiments confirm that evolution can and does exist.

  • Q:

    What is divergent evolution?

    A:

    Divergent evolution is the mechanism that causes different species to arise from common ancestors, the evolution toward greater difference in related organisms. In the classification system it is a part of, it is one of three types of evolution, the others being convergent evolution and coevolution. None of these types are truly separate, and in almost any case of convergent evolution or coevolution, divergent evolution is also occurring.

    What is mosaic evolution?

    A:

    Mosaic evolution occurs when the gene alleles of an organism or species evolve at different rates. Marks of mosaic evolution include the development of features within a species or organism at different times.
