How can the theory of evolution explain that man homo sapiens sapiens came from earlier species?

Homo sapiens are believed to have evolved from an earlier species, Homo erectus. Once hominids emerged around 2 million years ago, they migrated from Africa and populated the other continents. Several species of hominids existed simultaneously.
The earlier hominids included some which were much larger and more powerful than today's humans, and some smaller and weaker. They were not stoop-shouldered with short bow-legs and long arms, with hands dragging on the ground. They were just as upright as modern man, with feet and legs adapted to walking upright. There were also other great apes that (like today's chimps, gorillas and orang-utans) were not adapted to ground dwelling and thus never came into ecological competition with humans.
Today there are only 4 genera of great apes left -- Chimps, Gorillas, Orang-utans and humans. For a while, Gibbons were included in that group because they can raise their forearms above their heads like the other apes (old-world monkeys can't do that). But they are so different that they have been grouped in a class of their own.

Are organisms able to consciously direct the course of their own evolution?
No. Evolution is a consequence of selective pressure(s) from the environment acting on organisms. Virtually all living beings are not conscious of this process.The only species that *could* consciously direct its own evolution is Homo sapiens (humans), but currently it doesn't.Artificial selection can and has consciously directed evolution, but it always was a species acting over other different species, not on their own evolution.
If homo is genus of man what is the species?
the species of humans is sapiens.
What type of evolution is human evolution?
Human evolution is no different from the evolution of any other species of plant or animal. Over the course of hundreds of thousands of years our ancestors survived by being the better competitor for resources in their environment in their gene pool. The genes that enabled this better survivability were passed on, until the majority of the population were adapted to their environment etc:. homo habilis or homo sapiens or primates
How is angiosperm evolution related to insect evolution?
It is very simple to explain this concept. The more there is for a species to feed on, the more the species will thrive and multiply.
How do fossils help explain the theories of evolution?
Fossils give us a lot of information about species which used to exist on Earth but which are now extinct. With this information we can see in greater detail how species have evolved over time.
How did human evolution start?
Human evolution started with a species fron the homo called the HOMO SAPIENS.
What is the meaning of third sapiens in Homo sapiens sapiens?
The term "sapiens" in Homo sapiens sapiens means "wise" in Latin. The addition of "sapiens" to "Homo sapiens" distinguishes modern humans from earlier species within the Homo genus, emphasizing our advanced cognitive abilities.
What comes after neanderthal?
After Neanderthals, the next phase in human evolution is Homo sapiens, which are modern humans. Our species, Homo sapiens, emerged around 300,000 years ago and is the only surviving species of the genus Homo.
What will be the next developed species on the earth after homo sapiens sapiensor it is the last stage of development?
It is difficult to predict the next developed species after Homo sapiens sapiens. Evolution is a complex process influenced by various factors, so it is uncertain what form future species may take. Homo sapiens sapiens may not necessarily be the last stage of development, as evolution is an ongoing and dynamic phenomenon.
How were the first humans made when there were no human beings to reproduce?
The first humans are believed to have evolved over millions of years from earlier hominid species. Evolution is a gradual process where small changes over generations lead to the development of new species. It is thought that modern humans, Homo sapiens, emerged in Africa around 200,000 years ago.
What are these in the order they appeared on earth homo habilis homo sapiens australopithecines homo erectus neanderthals?
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.
What is the scientifical name for man?
The Latin name is Homo sapiens (knowing man, or rational man).Modern man is sometimes listed as a subspecies Homo sapiens sapiens to differentiate modern humans from Homo sapiens idaltu, an earlier hominid species that is very similar but not identical.
Human species name?
Homo sapiens, human species name
What theory states that most of Earth's current species developed from distinctly different species which existed earlier in time?
biological evolution ...........studyisland
How is the species Homo Sapiens different from earlier hominids?
Homo sapiens have a larger brain capacity, more advanced cognitive abilities, and the development of complex language and culture compared to earlier hominids. Additionally, they have a more refined tool-making ability and are characterized by bipedal locomotion.
What species are humans a member?
The species name for humans is sapiens. Our genus-species name is Homo sapiens.
Species is thought to be a direct ancestor of both Homo sapiens and Homo erectus?
The common ancestor of Homo sapiens and Homo erectus is thought to be Homo heidelbergensis, which lived around 700,000 years ago. This species is believed to have given rise to both Homo sapiens and Homo erectus through divergent evolution.
