Genes and Evolution: Selection, Genetic Drift, and a Calvin Klein Twist

The secret of life lies hidden in the genetic code.

Genes are fundamental in determining the characteristics

of an individual and passing on these characteristics to succeeding

generations. Occasionally, certain conditions produce

a structural change in the gene, which will bring about the

process of evolution.

This may occur in one or more of the following ways.

Firstly, by selective mating, in which a single gene

type proves superior in transmitting its genes to future

generations. Secondly, by gene

drift, in which certain genes may fade away

while other genes persist. And finally, by natural

selection, which filters out those genes better

equipped than others to

endure in the environment.

This may result in the origin of an entirely new species,

which brings us to Calvin's and the survival of the fittest
