" Once humans could see in color the visual inspection of a potential mate yielded far more useful information and at a greater distance than was the case with scents. As a result of natural selection color-seeing primates came to have neuronal wiring that caused them to place much more importance on appearance in mate choice. In Zhang's view it is therefore not coincidental that around the time human males developed the ability to see color humans also lost the ability to respond to pheromones" Evolution Of Color Eyesight Led To Loss Of Pheromone Response (URL accessed on 9 يناير، 2005) نسخة محفوظة 28 فبراير 2017 على موقع واي باك مشين.

"'Experiments with sex have been very hard to conduct,' Goddard said. 'In an experiment, one needs to hold all else constant, apart from the aspect of interest. This means that no higher organisms can be used, since they have to have sex to reproduce and therefore provide no asexual control.'

"Viruses of nearly all the major classes of organisms—animals, plants, fungi and bacteria/archaea—probably evolved with their hosts in the seas, given that most of the evolution of life on this planet has occurred there. This means that viruses also probably emerged from the waters with their different hosts, during the successive waves of colonisation of the terrestrial environment."

"A comparison of the two genomes reveals that both have about 30,000 genes, and they share the bulk of them—the human genome shares 99% of its genes with mice. Humans and mice diverged about 75 million years ago, too little time for many evolutionary differences to accumulate." Comparing genomes نسخة محفوظة 1 مارس 2012 على موقع واي باك مشين.
" Their conclusion: although the mouse and human genomes are very similar, genome rearrangements occurred more commonly than previously believed, accounting for the evolutionary distance between human and mouse from a common ancestor 75 million years ago." The Hindu نسخة محفوظة 14 نوفمبر 2010 على موقع واي باك مشين.
"Mice have many more olfactory genes compared to the human. Smell matters for mice, especially for sex and mating; they also have more genes involved in reproduction (such as aphrodisin, which stimulates mating behaviour in males) and immunity" San Francisco Chronicle نسخة محفوظة 14 نوفمبر 2010 على موقع واي باك مشين.
"I also wish to completely dispel the myth that the modern Great White evolved from the megalodon shark. Is the proper way to do this to write this paper, publish it in a scientific journal, and subject it to peer review—yes? Is that what I am doing—no.......because I think there is no way to "win" with the opinions on this one as set in stone as they seem to be (on both sides)" Origin of the Modern Great White Shark (URL accessed on 9 يناير، 2005)
"'Most scientists would probably say the Great Whites evolved from the megalodon line, which existed from two million to twenty million years ago. They were huge sharks, approximately the length of a Greyhound bus and possessing teeth that were up to six inches [150 mm] long,' explains Ciampaglio. 'However, our research, which is based on analyzing fossils of several hundred shark teeth, shows that the Great White shares more similarities with the mako shark.'"Great White Shark Evolution Debate (URL accessed on 9 يناير، 2005)

"Researchers have discovered fossilized remains of two previously unknown primate species that lived 37 million years ago in what is now the Egyptian desert." "The discovery, researchers say, is evidence that the common ancestor of living anthropoids arose in Africa and that anthropoids have been evolving on the now separated Africa-Arabia landmass for at least 45 million years."

" Once humans could see in color the visual inspection of a potential mate yielded far more useful information and at a greater distance than was the case with scents. As a result of natural selection color-seeing primates came to have neuronal wiring that caused them to place much more importance on appearance in mate choice. In Zhang's view it is therefore not coincidental that around the time human males developed the ability to see color humans also lost the ability to respond to pheromones" Evolution Of Color Eyesight Led To Loss Of Pheromone Response (URL accessed on 9 يناير، 2005) نسخة محفوظة 28 فبراير 2017 على موقع واي باك مشين.
