The tempo or speed with which evolution and subsequent speciation can occur varies greatly. Darwin assumed that evolution was a constant accumulation of new traits that leads to the formation of a new species. In more recent years, Stephen Jay Gould and Niles Eldrege proposed a second explanation. Which of the following observations best explains the punctuated equilibrium model?



A. Fossils that show many intermediate stages between a species of horse from 6 million years ago and the currently existing species.

B. Fossils with little or no changes exist in strata over several million years, but suddenly disappear and a similar but obviously new species appears in relatively brief geological period.

C. A mass extinction is followed by numerous new species appearing.

D. All of the above are examples of the punctuated equilibrium.

E. Choices 2 and 3 are both examples of the punctuated equilibrium mode

I know that certain things will make the bowel movement more disgusting: things such as boiled eggs and sausage. But what is happening in particular with this food to make it stinkier than others? It seems to be a common thread that the food is high in protein.

I just can't believe the odor that some people can manage to put out: an odor strong enough to cover the entire floor of an office building.

A recent article on the genetics of eye color said "There is no single gene for eye color," while an article on homosexuality said "Human behavior is way too complex for a single gene to determine sexual behavior."

If both parents have brown eyes, all aunts and uncles have brown eyes, and all grandparents have brown eyes there is still a 7 to 8% chance their child will not be brown eyed. If there is just one aunt or uncle with green or blue eyes, the chance of the child not being brown eyed rises to 11 to 12%. The 11 to 12% range remains constant if aunts or uncles from both parents are not brown eyed.

These percentages resemble scientific studies on the percentage homosexuality.

Although it is not known why being brown eyed is dominant, the assumption of heterosexuality being dominant could be explained as needed to propagate the species. Although brown eyes are dominant, there are still blue and green eyed individuals, as there are still gay homosexual and bisexual individuals.
