The categorization of the human species (systematic name: Homo sapiens) within zoological taxonomy is known as human taxonomy. Homo is a taxonomic genus that includes both anatomically contemporary humans and extinct forms of archaic humans. Sapiens is the extant species within this genus.
It has been suggested that because humans are such an integral part of the ecosystem, we should be classified among the animals rather than as a single species. Whether this is feasible within the limits of zoology is a matter of debate among scientists.
Currently, there are only two ways to classify organisms: by physical characteristics or by genetic similarities. Since humans cannot be described by either their features or their DNA, they must be grouped with other organisms that share similar attributes. Researchers use these groups, called taxa, to describe how many species exist within the human family. Scientists estimate that between 1,000 and 10,000 species have been identified so far. The exact number is unknown because new species continue to be discovered even today. However, it is estimated that we know about only about 5% of all living organisms on Earth.
Within the context of this article, the term "species" is used to describe unique individuals within a population who can reproduce with each other and not with individuals from another species. Although this definition appears straightforward, it is difficult to apply to humans due to our close relationship with other species.

Humans are scientifically known as Homo sapiens. The genus name, meaning "wise man", was given to reflect humanity's ability to learn and adapt through culture and technology.
The species name means "human being" or "people". It is used to indicate that humans are the highest form of life on earth.
Although humans are unique in many ways, they are not the only organism capable of learning and adapting through culture and technology. Other animals have been observed using tools, making nests, creating shelters, and storing food. Some even show evidence of having committed suicide. However these other organisms do not possess a full understanding of what it means to be human. Humans are the only creatures who can think critically and use language to analyze their environment and themselves.
As well as being unique, humans are also similar to other primates in many ways. We share 95% of our DNA with bananas, monkeys, and gorillas. Also like those animals, we communicate with each other through gestures and sounds. We use our intelligence to solve problems and explore new opportunities. And like those others, we die. But despite these similarities, humans are also uniquely different from other animals. For example, only humans can talk.
Homo Sapiens Homo sapiens is the scientific designation for humans. Humans are classified as mammalia and primates. Synthetic names are applied to groups of individuals that share a common characteristic, such as the name given to humans who share a recent common ancestor. This common ancestor is called the "protohuman" or "protoanthropus". Because modern humans share a very large number of genes with chimpanzees, many scientists consider humans and chimpanzees to be two species of a single genus. Human evolution, like that of other organisms, involves genetic changes that prevent some members of a population from surviving into later generations. Over time, these genetic changes will lead to a new species arising if all remaining members of the original species carry the change. This will always happen unless the original species dies out before this can occur. In this case, there would be no more individuals like our protohuman ancestor to evolve into today's humans.
Modern humans originated in Africa about 200,000 years ago. Genetic evidence shows that early humans lived largely on meat they hunted themselves. They also probably cooked and ate some plants, but the majority of their food was animal flesh. Modern humans spread from Africa to every part of the world where they were able to live using only their brains.
Homo sapiens (Latin for "wise man") is the species to which all contemporary humans belong. Homo sapiens is one of numerous species classified as Homo, but it is the only one that is not extinct. Modern humans originated in Africa about 200,000 years ago and migrated out of Africa about 50,000 years ago.
In biology, a human is an organism with a biological structure similar to that of modern humans and possessing distinguishing characteristics such as limbs, a head, and organs suitable for breathing air and producing milk. Humans differ from other primates by having hair, a need for oxygen to live, a brain, and a capacity for learning new things. Although scientists do not know exactly what causes some people to develop certain traits while others do not, genetics plays a role in determining who will have hair or eyes of different colors, etc.
The study of humans, human evolution, and human diversity is known as human biology. Scientists who study human biology include anthropologists, paleontologists, geneticists, physiologists, and neurologists.
Anthropology is the scientific study of humans, their behavior, and history. It is divided into three main branches: social anthropology, cultural anthropology, and evolutionary anthropology. Each branch has sub-fields such as psychoanalytic anthropology, political anthropology, and archaeological anthropology.
He included humans among the primates and introduced the usage of both genus and species designations for all animal identification. He coined the still-in-use scientific moniker Homo sapiens for the human species. He classified this species into four subspecies: H. americanus, H. africanus, H. europaeus, and H. asiaticus. He also noted differences between males and females of H. sapiens.
Charles Darwin's description of our species as "the highest creature on earth, so far as we know" has been cited by scientists as justification for maintaining its status as a unique entity within Charles Darwin University's taxonomy program.
However, some scientists believe that Homo neanderthalensis is the ancestor of H. sapiens and not the other way around as originally thought by Darwin. They base this conclusion on physical evidence that shows that early H. sapiens had significantly larger brains than modern Neanderthals. These scientists also note that there are similarities between ancient languages used by Neanderthals and those used by H. sapiens before they developed their own language systems. These facts lead some scientists to believe that H. sapiens evolved from H. neanderthalensis rather than the other way around as first believed by Darwin.
Other scientists believe that neither H. neanderthalensis nor H. sapiens are unique entities but that they belong to a group of several related species including Homo antecessor, Homo heidelbergensis, and Paranthropus boisei.
