Today many people still disagree with the theory of evolution. However, that is the nature of scientific progress. Darwin wasn’t the only advancement in building the evidence for evolution. The theory of evolution by natural selection developed over time and from information gathered by many scientists Lamarck's Theory of Evolution Another theory of evolution, developed at the start of the 19th century (before Darwin announced his theory), was that of French scientists Jean-Baptiste Lamarck Variation and adaptation – organisms are not all alike, organisms that are well-suited to survive in their environment possess adaptations Survival of the fittest – those organisms best adapted will survive and reproduce at higher rates than those who are not. 4.

Download scientific diagram | The conventional view of Darwinian evolutionary theory: An individual produces variations that are selected by the environment  Only variation that arises in germ cells can be inherited from one individual to another and so affect population dynamics, and ultimately evolution.

Variation exists regardless of organism's needs not directed towar Darwin och evolutionsteorin.

This field attempts to account for evolution in terms of changes in gene and genotype frequencies within populations and the processes that convert the variation with populations into more or less permanent variation between species.

The theory of evolution is one of the most widely accepted ways to explain all life on earth. At its center is how biology directs the evolution of species to create diversity and change in the natural world. Evolution is a theory about the origin of life.

A scientific theory gives explanations and predictions for naturally occurring phenomena based on observations and experimentations. This type of theory attempts to explain how events seen in the natural world work.

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.
