Homo Sapiens Saga: The Evolution of Homosapiens
The Journey from Apes to Humans: A Detailed Timeline The story of human evolution begins around 6-7 million years ago in Africa, where the last common ancestor of humans and chimpanzees lived. From there, a series of hominin species emerged, each contributing to the traits that define us today. Let’s walk through this journey step by step. 1. Sahelanthropus tchadensis (7-6 Million Years Ago) Timeline: 7-6 million years ago. Significance: One of the earliest known hominins, Sahelanthropus is considered a close relative of the last common ancestor of humans and chimpanzees. Key Features: It had a small brain (about 350 cc, similar to a chimp’s) but showed signs of bipedalism (walking on two legs), based on the position of its skull and spinal cord. Fossil Evidence: The famous "Toumai" skull, discovered in Chad in 2001, is the most complete fossil of this species. 2. Orrorin tugenensis (6 Million Years Ago) Timeline: Aroun...
