Species definition

A species is a group of living organisms that share similar physical characteristics and are capable of interbreeding to produce fertile offspring under natural conditions. Essentially, members of the same species are a distinct type of organism that can reproduce among themselves, ensuring their genetic traits are passed on. Different species are usually unable to produce fertile offspring together due to genetic differences, reproductive barriers, or other factors. This concept helps scientists categorize and understand the diversity of life on Earth, recognizing how each group fits into the broader web of biological relationships.
