Natural Selection and Charles Darwin's Legacy

The video discusses how scientists use fossil records to compare current species with ancient ones, highlighting Charles Darwin's contributions to the theory of evolution. Darwin's observations during his voyage on the HMS Beagle, particularly of finches in the Galapagos Islands, led to his theory of natural selection. This theory explains how species adapt to their environments over time. Despite initial controversy, Darwin's theory is now widely accepted, supported by further scientific research. The video concludes with review questions on Darwin's work.

What is the main idea behind natural selection?

• All species remain unchanged over time.
