The typical day would start with Huxley lecturing at 9am, followed by a program of laboratory work supervised by his demonstrators.

Mendel, Darwin and Evolution

Huxley's reservations on natural selection were of the type "until selection and breeding can be seen to give rise to varieties which are infertile with each other, natural selection cannot be proved". The first publication by Darwin of his ideas came when Wallace sent Darwin his famous paper on natural selection, which was presented by Lyell and Hooker to the Linnean Society in alongside excerpts from Darwin's notebook and a Darwin letter to Asa Gray.

There were two very big holes in the initial theory. The third law, the The Law of Dominance, states that one type of allele the dominant could mask the other the recessive. This led him directly into a clash with Richard Owena man widely disliked for his behaviour whilst also being admired for his capability.

New hybrid food strains were developed that were either more productive, more nutritious, more disease resistant or had better taste. Huxley's reply to the effect that he would rather be descended from an ape than a man who misused his great talents to suppress debate—the exact wording is not certain—was widely recounted in pamphlets and a spoof play.

On the other hand, Darwin viewed females as shopping around for mates with desirable genes while rejecting those with inferior genes.The theory of evolution by natural selection, first formulated in Darwin's book "On the Origin of Species" inis the process by which organisms change over time as a result of changes in.
