Are there any sub-species of human beings?
No. All extant humans are of the species Homo sapiens. The variation in modern human DNA is very small (about 0.1%) compared to other species, which suggests that all modern humans descend from a small group that lived about 100,000 years ago. No modern human group has been classified as a sub-species. However, H. neanderthalensis is sometimes classified as a sub species of H. sapiens (H. sapiens neanderthalensis).Several species of humans existed in the past. H. erectus spread out of Africa and into Europe and Asia almost 2 million years ago, long before modern humans evolved from a common ancestor in Africa around 200,000 years ago. H. erectus eventually evolved into other species, such as H. antecessor, H. heidelbergensisand H. neanderthalensis. Modern humans who migrated out of Africa around 70,000 years ago coexisted with H. neanderthalensis and other sister species and my have shared habitat with them for long periods of time. These sister species were extinct by about 33,000 years ago.
How long has the homo sapiens species existed?
Some 200,000 years the beginning of our species in Africa, tens of thousands of years these modern humans remained in the continent. Around the hundred thousand years ago one group made a brief foray into the Middle East but was unable to press on. Then about 70,000 years ago a small population out broke out of Africa. That lead to us taking over the world as the dominant species.
How long ago did the homo sapions sapions live?
Homo sapiens sapiens, which is the scientific name for modern humans, emerged around 200,000 years ago in Africa. This marked the beginning of our species as we know it today.
How long neanderthals been on earth?
Neanderthals lived on Earth for about 350,000 to 40,000 years ago. They are an extinct species of humans that are closely related to modern humans.
How long have humans existed?
About 5.6 Million years ago Human beings existed! They started off with the brain size of a peanut. They had hair all over. Pretty soon that stopped and they got a bigger brain and lost hair. And now this is the way it is!
The change in the inherited traits of species over long periods of time is called?
Evolve.
If evolution is true then why there is no species excisting in between chimpansie and human?
Humans did not evolve from chimpanzees, rather both humans and chimpanzees share a common ancestor. A division happened with this common ancestor....some went on to become chimpanzees and some went on to become modern humans. There are common ancestors to both humans and chimps, but they are long extinct.

What theory proposes species evolve during short periods of rapid change?
Punctuated equilibrium theory proposes that species evolve rapidly during short periods of significant change, followed by long periods of stability with little evolutionary change. This contrasts with gradualism, which suggests that evolution occurs steadily over long periods of time.
Why cant new species evolve from natural selection?
New species can evolve through natural selection over long periods of time. However, the process is complex and can take thousands to millions of years due to the gradual accumulation of genetic changes and adaptations. The formation of new species also depends on various factors such as environmental changes, genetic variation, and reproductive isolation.
Why do new species form?
According to the biological species concept, when the new species no longer can interbreed with the ancestral species, or with the population that it has been geographically isolated from long enough to have allele change significantly enough to prevent interbreeding.
How long have there been human-like animals on the earth?
Human-like animals, known as hominids, have been around for several million years. The earliest hominids appeared around 7 million years ago, evolving into various species over time. The modern human species, Homo sapiens, emerged around 300,000 years ago.
How long has the modern human been in existence?
It depend in our creator and that is god
Who was the discoverer of fire?
Almost certainly some nonhuman ancestor of modern humans whose species has long since gone extinct, as archeological evidence seems to indicate all modern human populations have always had and used fire. Names of nonhuman ancestors aren't available.
When did the hypohippus appear and into what organisms did it likely evolve?
Hypohippus appeared during the Miocene epoch, around 23-5 million years ago. It likely evolved into modern-day horses and related equine species.
What do organisms change into over long periods of time?
Organisms can evolve into new species over long periods of time through the process of natural selection and adaptation to their environment. This can result in the development of new characteristics and the divergence of populations into separate species.
When will flies become extinct?
Flies will likely continue to evolve for another 1.1 billion years before extinction. The current species will have gone extinct (replaced with a new species of Fly) long before then.
