Richard Dawkins, is a British ethologist, evolutionary biologist and author.
Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.
He was the Professor for Public Understanding of Science at Oxford University from 1995 to 2008.

Ignorance or Stupidity?

This is why you should never speak in public about stuff you don't know. In here, you can see some of the worse answers of Miss America candidates to the question "Should Evolution be thought in school?".
Not sure if funny or really sad.

Evolution of Mickey Mouse

Mickey Mouse has evolved. This was noticed and brough to the world by Stephen J. Gould in his book, "The Panda's Thumb", deserving a whole chapter.
As you can see, in this case, Mickey Mouse is not portraited as an individual, but as a population, or species of consecutive Mickeys. The Mickeys started to suffer small changes and, since they were successful (the character became more dear to the public) they kept those traits, by a special kind of natural selection.

His most important contribute to this science was the Theory of Pontuated Equilibrium, a line of thinling that, diferently from gradualism, defends that short periods where many evolution steps occour are separated by long peroid where only a few happen.
Some of his books, like the "The Panda's Thumb" or "Eight Little Piggies" are still being edited after decades.

Maynard Smith was an unconventional professor for his time, trully dedicated to young resserchers and helping them develop their works. The only one he could not help was Hamilton, student in the same college. Hamilton was so afraid that someone would steal his work that he didn't try to find help.

Do individuals genetically adapt to their environments?

Hello,
today I'm going to talk about another evolution myth: many people actually believe that the evolution theory deffends that individuals can freely adapt to the environment, surviving.
This is nothing but an incorrect interpretation of the theory. This idea is really a misconception, and reffers to LaMark's way in trying to explain evolution, way befforre Darwin's publication of his Origin of the Species.

Infanticide among free-ranging langurs

Even though this happens in some other species, different kinds of explanations may be given, like regulation of population density, social stress, social crowding, sexual frustration, incest avoidance, or social bonding.
Recent studies promote a new hypothesis: Since they are not monogamic, males kill younglings from other males, so that the female may become receptive to him.
This may be an example of how the "selfish gene" tries to protect its transmition to the new generation in the largest number possible.
