Like cement sets the foundation for a house‚ the cell theory sets the foundation for biology. Schleiden and Schwann proposed the cell theory‚ which states that the cell is the basic unit of life and that new cells arise only from the reproduction of already existing cells via cell cycle‚ in 1839. Since the cell is the structural and functional unit of life as the house is for a community‚ without the house the community would be irritated and would not be stable‚ the community would therefore cease

Relation to Sex. In the former‚ he presents his theory of natural selection that results from the struggle to survive (On the Origin of Species‚ 175). In the latter‚ he explains sexual selection that results from the struggle to reproduce. According to Darwin‚ natural selection is one the basic agents of evolutionary change. At the same time‚ sexual selection is divided into the two aspects of intrasexual and intersexual selection. In essence‚ natural selection involves the success of both sexes with respect

That man is Charles Darwin‚ a British born naturalist and geologist‚ who created the theories of Evolution and Natural Selection.

His smooth and fluent style‚ helps the reader gracefully follow along. Though his findings inspired many scientists to scientifically analyze his claims‚ Darwin’s studies were not with in the realm of science. Rather‚ his findings are logical which he found by studying various species among the natural world over a long period of time. The use of constant examples

The Theory of Natural Selection was first introduced by Charles Darwin. While on a voyage to the Galapagos Darwin observed how animals possess certain traits that allowed them “the best chance of survival”. The basic concept of natural selection is that the animals with traits considered advantageous are able to reproduce more offspring then animals that do not have these traits. The precepts of this theory are manifested by observing animals and their traits. In his book The Origin of Species Darwin

He embarked on a five-year journey around the world simply keeping the captain company. He studied specimens‚ which led him to formulate his theory of evolution and his views on the process of natural selection. He proposed the theory of evolution due to his curiosity of the configurations he had seen. A group of species could belong together‚ but contain special features that help it to survive in its specific environment. For example‚ Darwin

Here we have some highlights of how the natural selection works and some of the evolutionary forces that drive evolution: The natural selection operates in base of the difference between de reproductive successes of the individuals. The genes of the most successful individuals (the ones that reproduces more) appears more in the next generation. If an individual cannot survive it will not be able to reproduce. Because of that natural selection is NOT RANDOM and can act really quickly. (Charlat et
