An Introduction to Evolutionary Biology: Threads in the Web of Life

The field of evolutionary biology provides irrefutable evidence that all life on Earth is complex, dynamic, and ever-changing. This branch of science primarily aims to decipher the mechanisms and processes that, over the course of millions of years, have molded the astonishing variety of living creatures. Biological systems' history, present, and potential future can be better understood with the help of the principles and concepts that form the bedrock of evolutionary biology. First, Darwinian Evolution: A Foundational Theory

Charles Darwin's seminal work unquestionably established the groundwork of evolutionary biology. Natural selection, which Darwin proposed in his 1859 book "On the Origin of Species," is the primary mechanism by which species undergo evolutionary change. Evolutionary theory was built on the principle of natural selection, which states that organisms with greater adaptations to their environments have a better chance of survival and reproduction. This process clarified how different kinds of life may evolve through time by modifying their own characteristics.
