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.Know More
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.Learn more about Biology
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.Full Answer >
The theory of evolution proposed by Charles Darwin entails the evolution by natural selection of all life on earth. It states that new generations are born with different inheritable traits, and that the traits that are superior for survival will be passed on to new generations. This means that given enough time, an organism can change and evolve to create a new species.Full Answer >
Organic materials are substances in the soil that were once alive. Dead plants, animals, bacteria and fungi are all examples of organic material. Organic material is distinguished from organic matter by the amount of decomposition that has taken place. Organic matter has decomposed as much as it can.Full Answer >
An example of convergent evolution is the similar overall body structure of sharks and dolphins. The shark is a fish while the dolphin is a mammal, but their bodies have evolved to become similar. Another example is the adaptations for gliding found in both sugar gliders and flying squirrels.Full Answer >
