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
Biological evolution is defined as organisms reproducing but experiencing changes with each generation. Evolution can happen in a small and large context. There are small genetic changes between generations, as well as large changes that happen over multiple generations.Full Answer >
In scientific terms, evolution is both a theory and a fact. A fact refers to a scientific explanation that has been tested and confirmed often enough that there is no reason to keep looking for additional examples. Scientists accept evolution as a fact due to overwhelming evidence supporting it.Full Answer >
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.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 >
