Humans (Homo sapiens, meaning "thinking man" or "wise man") or modern humans are the most common and widespread species of primate, and the last surviving species of the genus Homo. They are great apes characterized by their hairlessness, bipedalism, and high intelligence.
The long evolutionary journey that created modern humans began with a single step—or more accurately—with the ability to walk on two legs. One of our earliest-known ancestors, Sahelanthropus ...
Harvard researchers question the onset of human life, emphasizing the critical nature of the 14-day embryonic stage influenced by new scientific and aging studies insights.
human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed zoologically, we humans are Homo sapiens, a culture -bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.
Life comprises individuals, living beings, assignable to groups (taxa). Each individual is composed of one or more minimal living units, called cells, and is capable of transformation of carbon -based and other compounds (metabolism), growth, and participation in reproductive acts.
Part of what it means to be human is how we became human. Over a long period of time, as early humans adapted to a changing world, they evolved certain characteristics that help define our species today.
The story of human evolution began about 7 million years ago, when the lineages that lead to Homo sapiens and chimpanzees separated.
The timeline of human evolution outlines the major events in the evolutionary lineage of the modern human species, Homo sapiens, throughout the history of life, beginning some 4 billion years ago down to recent evolution within H. sapiens during and since the Last Glacial Period.
First things first: A “human” is anyone who belongs to the genus Homo (Latin for “man”). Scientists still don’t know exactly when or how the first humans evolved, but they’ve identified a few...
The origins of humankind have long fascinated scientists and the public alike—but the topic can get confusing. Here are answers to a few common questions.
