The English biologist discovered the fact that species better adapt to their environment over time by developing, modifying, repurposing, and losing inheritable characteristics. However, Darwin did not understand the mechanism behind how species change.What Darwin did not know was genes and subsequently their mutation.
Between 1907 and 1963 more than 64,000 Americans were forcibly sterilized for common good. Can "bad seeds" be weeded out by force sterilization?
The Irish Potato Famine, also called the great famine, was a period of mass starvation and disease in Ireland from 1845 to 1852. The great famine claimed one million lives and caused millions to flee their country. In the aftermath…
Natural selection says only the fit will surprise. The fit are those that have the inherited traits that help them best adapt to their habitat so that they live long enough to have and raise their offspring. Does this mean all of the inheritable traits of organisms ultimately serve one purpose: improve the adaptation of the organisms to their environments?
Virtually all live-born babies grow up to have their own babies. Does this mean human natural selection, hence the evolution of humans, is coming to an end?
Potatoes grown by cloning are cheap and plentiful, but they share the same genetic information, which makes them vulnerable to the same potato diseases.
Evolutionary theory does not say any given species can evolve into totally different species. Evolution is about the accumulation of slight changes in new generations of species.
