Why it is incorrect to describe human evolution as a ‘ladder’ leading to Homo sapiens. Introduction: Organisms of hominin lineage (extinct species) are closely related to humans than those of their ancestors, apes. These species differ among themselves in brain and body size, diet, use of tools, and teeth morphology. Hominins evolved into present day Homo sapiens through various physiological changes. These changes were their adaptations to develop into modern day humans.
