Beneficial variations make the individuals more suitable to survive in the struggle for existence while harmgul variation causes its bearer unfit in the race and hence they are deprived of the chance to survive and reproduce. Evolution requires existing variation in the species. For example, giraffes with a random variation of an unusually long neck were better able to reach leaves in the canopy, making them fitter to survive and more likely to reproduce. Offspring with the same variation of a longer neck enjoyed the same evolutionary advantage at feeding time. Darwin's Theory of Evolution is a slow gradual process.

For example, giraffes with a random variation of an unusually long neck were better able to reach leaves in the canopy, making them fitter to survive and more likely to reproduce. Offspring with the same variation of a longer neck enjoyed the same evolutionary advantage at feeding time. The synthetic theory of evolution describes the evolution in terms of genetic variations in a population that leads to the formation of a new species. It explains the contribution of factors such as genetic variations, reproductive and geographical isolation, and natural selection.

His theory sets about explaining the progressive changes that occur within species down the generations, as well as the formation of new species, when environmental pressures have differential effects on the reproductive success of all individuals.

The theory of evolution by natural selection was only gradually accepted because: There was much controversy surrounding these revolutionary new ideas; The theory challenged the idea that God made all the animals and plants that live on Earth; There was insufficient evidence at the time the theory was published to convince many scientists; The mechanism of inheritance and variation was not
Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories. Modern or synthetic theory of evolution was designated by Huxley (1942). the whole process of natural selection is to some degree dependent on the idea of variation that within any population of a species you have some genetic variation so for example you know let's say I have a bunch of well this is the circle species and you know one guy is that color and then I got a bunch more maybe some are that color that's the same color that one and that one in that one and On the basis of above observations, Hugo de Vries (1901) put forward a theory of evolution, called mutation theory. The theory states that evolution is a jerky process where new varieties and species are formed by mutations (discontinuous variations) that function as raw material of evolution. The salient features of mutation theory are: 2020-07-26 · Genetic variation, as well as changes in the environment, cause characteristics of organisms to change over time.
