Human evolution Human evolution is the lengthy process of change by which people originated from apelike ancestors. Scientific evidence shows that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years. One of the earliest defining human traits, bipedalism -- the ability to walk on two legs , Evolution of Human Characteristics of Evolution of Humans The skulls were smaller in size than that of the current man. The volume of the brain between 600-700 c.c. Human had higher brows than in chimps and the face had more prominent facial structure. Distinct edges of the forehead were clear and easily identifiable. The occipital condyles were ventrally positioned The back of the skull was , Evolutionary biologists are interested in understanding how humans fit into the history of life and how the processes of evolution have shaped us. Much scientific effort goes into studying human evolution, and as a result, our understanding of this area is moving forward rapidly, as new evidence emerges and hypotheses are tested, confirmed, discarded, or modified., “In general, estimating ages with genetics is imprecise,” says Joshua Akey, who studies evolution of the human genome at Princeton University., Human evolution is a captivating journey that spans millions of years, revealing how our ancestors adapted, survived, and thrived. Ever wondered how we went from tree-dwelling primates to the complex beings we are today? Evolution isn't just about physical changes; it's also about the development of behaviors, tools, and societies. From the discovery of fire to the creation of intricate , What are the major milestones in human evolution? The human lineage diverged from that of apes at least seven million years ago and maybe as long as 13 million years ago..
