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.
When their food sources depleted our ancestors moved to areas where they would have access to meat and vegetation. It was thanks to agriculture humans could settle in, which irreversibly changed the course of history.
English biologist Charles Darwin was a European man of his time. Like many of his peers, he was under the impression that white men were inherently superior to women and people of color. Does the worldview of Darwin say anything about his theory and today's evolutionary biology?
Between 1907 and 1963 more than 64,000 Americans were forcibly sterilized for common good. Can "bad seeds" be weeded out by force sterilization?
Today the theory of evolution is a complex body of theory supported by other branches of science. In other words, we do not need the theory of evolution to know that evolution is a fact. However, in the mid-nineteenth century, the world was different.
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…
Evolution theory, also known as evolutionary theory, or the theory of evolution, is based on the idea that all life on earth is related and gradually changes over time. The theory primarily explains the ongoing speciation of life since its emergence on Earth.
In the second of the nineteenth century a fierce debate broke in the scientific community about Darwin's theory of evolution. However, by the twentieth century the debate was over.
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?
