 “Dispersal” is important in biology. Many amazing biological devices have evolved to ensure it, such as the production of fruits and nectar by plants and the provision of tasty protuberances called elaiosomes by seeds to attract insects. Often a species will produce two forms:

Updated AP History Rubrics
The updated rubrics for the AP history free-response questions are now available (.pdf/). Annotated sample essays scored with these rubrics will be available in late August.
It’s impossible to know the details of how our rush to extinction will play itself out, but we do know that it is going to be hell for those who are unlucky to be alive at the time.
One of the problems of selection at the group level is that of free-riders. These are people who take more than their share and contribute to the common good of the group less than their proper share. Selection at the group level gives free-riders their free ride. They potentially could increase until they destroy the cooperative fabric of the group.
Overshoot and collapse is common. See Human and nature dynamics (HANDY): Modeling inequality and use of resources in the collapse or sustainability of societies
The above loop was repeated countless thousands of times during the millions of years that we were evolving . This behavior is inherent in the architecture of our minds is entrained in our biological material and will be repeated until we go extinct. Carrying capacity will decline  with each future iteration of the overshoot loop, and this will cause human numbers to decline until they reach levels not seen since the Pleistocene.
