Biology – Evolution and Natural Selection
... Evolution by Natural Selection In nature, organisms with the best characteristics for surviving in an environment will live longer and pass those characteristics on to more offspring. Eventually more of the population will have these adaptive traits. ...

Study demonstrates evolutionary `fitness` not the most important
... Ard Louis: We are arguing that some biological traits may be found in nature not because they are fitter than other potential traits but simply because they are easier to find by evolution. Darwinian evolution proceeds in two steps. Firstly, there is variation: due to mutations, different members of ...

Theories on Origin and Change
... Scientists do not know how life first began or how evolutionary changes occurred. To explain these events, scientists have proposed various theories. Some theories have been totally rejected because of lack of supporting evidence. Other theories have been modified (changed) based on new evidence. ...
