evolutionary stages

Evolutionary stages refer to the gradual process through which living organisms develop and change over time. Starting with simple life forms, such as single-celled organisms, evolution progresses through natural selection, where traits that enhance survival and reproduction are passed on. As environments change, species adapt, leading to the emergence of diverse forms, from fish to mammals and eventually humans. These stages illustrate how complex life arises from simpler beginnings, driven by genetic variations and environmental pressures. Understanding these stages helps us appreciate the interconnectedness of all living beings and the dynamic nature of life on Earth.
