The body's natural defense against such cell invasion is to release certain proteins, called antigens, which "plug up" the receptor sites on healthy cells. This causes the foreign virus to not have a docking point on the cell. This process, however, is slow and not effective against a new viral attack. Genetic engineering is improving the body's defenses by creating pure antige...

481 wordsNatural selection, or survival of the fittest, is an evolutionary shift in a species. It occurs when member or members of a species possess specific genetic traits (natural or a mutation) that are beneficial to their survival in a particular environment. Those that survive because of that trait are obviously the only left to reproduce and the trait carries over to their offspring, and becomes common to that species. This theory was observed by Darwin, and presented in his book Origin of Species ...
