After watching this video in its entirety‚ I fond there to be quite a few things that she had said to be interesting to me. The example in particular that I found to be the most interesting was when she discussed the concept that in many species‚ there are several genders of males. Dr. Roughgarden explained a bird species called the Ruff‚ the males have different colors‚ and some males have no colors at all. She explained that during mating‚ the males with the black collar go into an area called

Life in the Universe In this talk‚ I would like to speculate a little‚ on the development of life in the universe‚ and in particular‚ the development of intelligent life. I shall take this to include the human race‚ even though much of its behaviour through out history‚ has been pretty stupid‚ and not calculated to aid the survival of the species. Two questions I shall discuss are‚ ’What is the probability of life existing else where in the universe?’ and‚ ’How may life develop in

Adaptive phenotypic plasticity is being increasingly recognized as an important role in adaptive radiation. The plasticity leads to the production of phenotypes that are well suited for the ecological niches. The Midas cichlid fish‚ which are distributed in the Nicaraguan great lakes and several crater lakes‚ have been known for their intraspecific polymorphism‚ and phenotypic plasticity. The lower pharyngeal jaw of the Midas cichlid fish Amphilophus citrinellus was tested in different diets for

I will be arguing for Cartesian dualism in this paper. I will argue that Cartesian dualism offers a more reasonable explanation of reality than Darwinian monism. I believe that the mind and the body are two separate things. Life did not just happen by chance. Someone or someone’s mind‚ created this universe. For anything to take place someone has to have made the first move. “Now whatever is in motion is put in motion by another‚ for nothing can be in motion except it is in potentially to that towards

The theory of social Darwinism commonly refers to ideas that predate Darwin’s publication of an origin of species. Social darwinism is the theory the individuals‚ groups and peoples are subject to the same Darwinian laws of natural selection as plants and animals. Now largely discredited‚ it was advocated by Herbert spencer and others in late 19th century and early 20th century and was used to justify political conservatism‚ imperialism‚ and racism and discourage intervention and reform.
