Unity of Life

Unity of Life refers to the concept that all living organisms share a common ancestry and fundamental biological processes, despite their diversity. This idea suggests that different species, from plants and animals to microorganisms, have evolved over billions of years from shared ancestors. Key evidence includes similarities in genetic material, cellular structures, and metabolic pathways. This principle underlies the study of biology, emphasizing that while life presents in various forms and functions, all organisms are interconnected through evolutionary history and essential life processes, highlighting the shared characteristics that unify all living things on Earth.
