Evolutionary biology. Evolutionary thought, the recognition that species change over time and the perceived understanding of how such processes work, has roots in antiquity—in the ideas of the ancient Greeks, Romans, Chinese, Church Fathers as well as in medieval Islamic science. With the beginnings of modern biological taxonomy in the late ...
The most widely accepted model of planetary formation is known as the nebular hypothesis. This model posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years. Many stars, including the Sun, were formed within this collapsing cloud.

Gemmules were thought to develop into their associated body parts as offspring matures. The theory implied that changes to the body during an organism's life ...
Polygenism. Polygenism is a theory of human origins which posits the view that the human races are of different origins ( polygenesis ). This view is opposite to the idea of monogenism, which posits a single origin of humanity. Modern scientific views find little merit in any polygenic model due to an increased understanding of speciation in a ...
