Humans, or Homo sapiens, belong to the genus Homo and have been present on Earth for around 300,000 years. They are believed to have evolved from earlier species of hominids, such as Homo erectus and Homo habilis. The exact order of appearance of different Homo species is still a subject of research and debate among scientists.
Humans are believed to have evolved around 200,000 years ago in Africa. The exact timing of when the first human-like species appeared is still an area of active research and debate among scientists studying human origins.
"Earthling", or, since it would amazingly impossible for an identical human species to form somewhere else in the universe, "Human"
The exact timeline of when the first human being was alive on Earth is not definitively known. It is believed that Homo sapiens, the species to which modern humans belong, emerged in Africa around 300,000 years ago based on current fossil and genetic evidence.
Most human activities take place in the layer of the atmosphere known as the troposphere. This is the lowest part of the atmosphere of the earth.
Most human activity takes place in the troposphere, which is the lowest layer of Earth's atmosphere. It is where weather phenomenon, such as clouds and storm, occur. This layer extends from the Earth's surface up to approximately 10-15 kilometers in altitude.
The human species that appeared first on Earth is Homo habilis, followed by Homo erectus, then Homo sapiens (modern humans).
The order in which these species appeared on Earth is australopithecines, homo habilis, homo erectus, neanderthals, and finally homo sapiens. Each of these species represents different stages of human evolution, with homo sapiens being the most recent and the only surviving species.
The last human species to live on Earth alongside Homo sapiens was Neanderthals. They coexisted with our species for thousands of years before eventually going extinct around 40,000 years ago.
Length of time species has existed on earth
Human's are considered the highest species of mammals on the Earth. But then, as a human, I'm rather biased!
Homo erectus is believed to have appeared around 1.9 million years ago, making it one of the early human species, but not the second to appear on Earth. Homo erectus is considered an ancestor of modern humans and existed before other species like Homo sapiens.
that was me
Humans are believed to have evolved around 200,000 years ago in Africa. The exact timing of when the first human-like species appeared is still an area of active research and debate among scientists studying human origins.

True
There are almost 4 thousand different species of mammals including human beings.
You are human because God made you that way!
