Genetic variations and evolution 8 Articles

by Briar Shaw

In 1953 Watson and Crick, of Cambridge University, published the first big breakthrough in our understanding of how genetic variation works on evolution. Before this, we knew that there is genetic variability, and that it...read more

Genetic variation is the mainstay component of modern evolutionary theory. At its most basic level it is also fairly easy to understand, as it can be observed by anyone from any walk of life. Look at the people around y...read more

Genetic Variation is a driving force in the evolution of species. Variation occurs in different ways, one of the primary ones being of course mutation. When considering the complexity of DNA it is not surprising that w...read more

Evolution is the theory that living creatures, animal, plant and single celled organisms, adapt to changes in their environment over multiple generations. This has been summarized by the statement "The strong survive," o...read more

Evolution would not be possible without genetic variation. If every individual in a species had the exact same genes, that species could not evolve. Natural selection, however, does not work directly on genes, and Charles...read more

The most important factor in the evolution of species is genetic variation. DNA polymers are practically infinitesimal, but still can contain over 200 million base pairings. Even with this many different pairings, a sing...read more

Natural selection has often been defined as "survival of the fittest." More appropriately, natural selection is the differential survival and reproduction of organisms that are best suited for their environment. In ...read more

The vast palette of genetic variations within a species DNA for the most part lies dormant and unseen. For example, the earliest dogs were thought to have been all under fifty pounds, having hook-shaped tails and mostly p...read more
