|
Pauperization
|
Refers to thedestruction that our species has caused the earth by essentially poisoning theworld. The specific ways can be divided into five categories: habitat loss,invasive species, pollution, human over-population, and over-harvesting. |
|
Niche |
Wilsonexplained that humans have a small “niche”. What he means by this is thathumans require a very specific environment in order to survive. With ourcurrent actions, more and more we are destroying this environment and thenecessities for human survival. |

False |
|
There is a strongcorrelation between human population growth and extinction rate |
True |
|
NegativeFeedback loop |
Whensomething is causing a change in a system, and then a response occurs to bringthe original change back to a homeostasis (EX: Humans are making the earthhotter and hotter...if we stop doing the things we are doing to make it so hot,the earth will naturally return to its optimum temperature...i.e. Return tohomeostasis.) |

Evolution:
|
change in the genetic makeup of a population (gene pool) over time |

Natural Selection
|
Rhe classic term that means survival of the fittest… If a certain individual has specific characteristics or advantages that help them survive better in their own environment, they will more likely be the individual that survives longer over time and can pass on his or her genes through reproduction |

Emigration:
|
IS when an individual moves out of their original niche or habitat

a point in history when a population was greatly reduced and eventually recovered, but the few individuals that started the new population were completely random. Their traits had nothing to do with their survival...they just got lucky (RANDOM!!!!)
|
|
Founder effect:
|
when a population is split up by chance, and the two new populations gene pools begin to differ because the new genetic makeup of the population will cause the two populations to possibly become their own species
|

|
|
Rivet-popping hypothesis:
|
Extinction of species is like losing rivets on a wing of a plane. If you use a few, it’s fine because others will hold it up. If you lose too many, everything will fall apart. Other species can take its place until they all run out.

|
How are human infectious diseases doing? |
The warmer it gets, the more mosquitoes, flies, ticks, will be able to carry and spread diseases because of the longer warm season.
