Evolutionary biology is a scientific study that focuses on the processes and mechanisms associated with life diversity and adaptation on earth. The study field is centered on how species change with time due to mechanisms of natural selection, genetic drift, or gene flow which give rise to new species and the extinction of others.

The most crucial concept that underlines evolutionary biology was first proposed by Charles Darwin as natural selection. Natural selection hypothesizes that the individuals having traits which are better suited to their environment will survive and reproduce more, thus passing those advantageous traits to their offspring. In doing so, through some time, adaptation of species to their environments and the evolution of new species occur.

Evolutionary biology relies on many techniques and technologies in its research, such as comparative anatomy-this is the comparison of similarities and differences in the structure of various organisms-and molecular biology-an organism’s genetic material to demonstrate evolutionary relationships. The fossil record essentially provides historical evidence of past forms of life and evolutionary transitions, while phylogenetics makes use of a set of genetic data to reconstruct the patterns of evolutionary change which underlie relationships between species.

Evolutive biology is the study of the evolutionary process and its influence on behavior, development, and disease. If understood, these fields explain a great deal of complexity in life and shape ecology, conservation biology, and medicine.

Such study leads to greater understanding in how life evolves and adapts, crucial for addressing the challenges in biodiversity loss, environmental change, and the impacts that the evolutionary process have on human health.
