In July 2012, Ancestry.com reported on historic and DNA research by its staff that discovered that Obama is likely a descendant through his mother of John Punch, considered by some historians to be the first African slave in the Virginia colony. An indentured servant, he was "bound for life" in 1640 after trying to escape. The story of him and his descendants is that of multi-racial America since it appeared he and his sons married or had unions with white women, likely indentured servants and working-class like them. Their multi-racial children were free because they were born to free English women. Over time, Obama's line of the Bunch family (as they became known) were property owners and continued to "marry white"; they became part of white society, likely by the early to mid-18th century.
Who is John Punch?
A: the first African slave in the Virginia colony

The Watch Tower Society rejects accusations that it is a false prophet, stating that its teachings are not inspired or infallible, and that it has not claimed its predictions were "the words of Jehovah." George D. Chryssides has suggested that with the exception of statements about 1914, 1925 and 1975, the changing views and dates of the Jehovah's Witnesses are largely attributable to changed understandings of biblical chronology than to failed predictions. Chryssides further states, "it is therefore simplistic and naïve to view the Witnesses as a group that continues to set a single end-date that fails and then devise a new one, as many counter-cultists do." However, sociologist Andrew Holden states that since the foundation of the movement around 140 years ago, "Witnesses have maintained that we are living on the precipice of the end of time."
What does George D. Chryssides suggest the changing views and dates of the Jehovah's Witnesses can be attributed to changed understandings of?
A: biblical chronology

Pesticides are used to control organisms that are considered to be harmful. For example, they are used to kill mosquitoes that can transmit potentially deadly diseases like West Nile virus, yellow fever, and malaria. They can also kill bees, wasps or ants that can cause allergic reactions. Insecticides can protect animals from illnesses that can be caused by parasites such as fleas. Pesticides can prevent sickness in humans that could be caused by moldy food or diseased produce. Herbicides can be used to clear roadside weeds, trees and brush. They can also kill invasive weeds that may cause environmental damage. Herbicides are commonly applied in ponds and lakes to control algae and plants such as water grasses that can interfere with activities like swimming and fishing and cause the water to look or smell unpleasant. Uncontrolled pests such as termites and mold can damage structures such as houses. Pesticides are used in grocery stores and food storage facilities to manage rodents and insects that infest food such as grain. Each use of a pesticide carries some associated risk. Proper pesticide use decreases these associated risks to a level deemed acceptable by pesticide regulatory agencies such as the United States Environmental Protection Agency (EPA) and the Pest Management Regulatory Agency (PMRA) of Canada.
