Natural selection

Natural selection occurs due to a series of steps


⇒  Organisms show a wide range of variation due to the genes they possess.


⇒  These genes allow them to survive in particular environments, because

      they survive they are able to pass on their genes.


⇒  The genes passed on to the offspring also allows them to survive Those

      without the genes are not able to compete for food or shelter and will

      soon die


⇒   Over time only certain individuals within a species will exist as they evolve

       and out compete others


Not everyone agreed with Darwin and many scientists had different views.

A key viewpoint was that of Lamarck’s.

Lamarck argued that the characteristics used a lot by the organisms would

then be developed and passed on to the next generation.
