If over 100 years ago, Don Francisco Felix deSouza was known as the King of Slavery in Ouidah, Bening. deSouza was a Portuguese national from Brazil who supervised the expulsion of hundreds of thousands of enslaved Africans out of Ouidah (a port on the West African Atlantic coast) to the Western Hemisphere. As the King of Portugal's personal emissar to maintain Portugal's investment in the transatlantic slave trade, deSouza remained in Ouidah for much of his adult life. He became extremely rich from the sale of Africans and while residing in West Africa he fathered, with hundreds of African women, 99 sons, and an unkown number of daughters. Today, 2,000 of his direct descendants now live in Ouidah (currently a town of about 40,000 individuals) and many more are indirectly related to him. Genes derived from deSouza are disproportionately represented among the town's residents. What is this an example of?

True or False. In terms of obesity, what's happening today is that we've changed the environment that we live in such an incredibly short time- one generation or perhaps two generations at most, and this has challenged our ancient metabolism, which for thousands of generations has been geared to fight famine.
Definition
True
Term

True/False

In the last period of global warming, mammals and the primates thrived which led to their survival and global dominance. Currently small animals and insects (like the birsd, squirrels and mosquitoes) tend to have large population sizes and short generation times. Large population size means that the species is more likely to have the genetic variation necessary for evolution, and having a short generation time means that their rate of evolutionary change may be able to keep pace with environmental change. All tehse facors may result in their ultimate survival during a period of global warming

Definition
TRUE
Term

In an attempt to re-establish the Bearded Vulture Population back into the wild, several biologists from Frankfurt Zoological Society created an introduction program. They have released many of the captive bearded vultures and a good number of them have survived. A problem with this program was proposed, stating that the population size of the captive birds [120] is not nearly large enough to provide the genetic variability crucial to the survival of these birds.

Speciation can occur when a factor separates a population for a significant amount of time.
