I'm not any kind of expert, but anybody can look at the original research paper,, and see what was identified as human-like and what was identified as not like them. I go into the main details on my blog, Fundamentalist Science.
The significant features tied to our genus are the general shape of the head, the small teeth, and features of the hands and feet. They mention size, too, but humans come in a wide range of sizes and so do apes.
Now, on the other side is "a more primitive or australopith-like trunk, ... shoulder," and "pelvis and proximal femur." Just those alone seem to argue strongly against giving the nod to placing the critter on the human side of the equation. Everything at its core is like an ausralopithecine "ape" or non-human. What seems to put the weight on the side of "non-human" to me is the tiny size of the brain. Even the fossils assigned to our genus, such as H. erectus, have distinctly larger brains.
Maybe there's some technical reason for assigning naledi to our genus, but I don't think something that is so much like an ape with human-like hands and feet makes the cut.
Linnaean taxonomy is a system of classification that divides all living things into hierarchical groups based on their characteristics. (i.e Living things are divided into groups, the groups are then divided into smaller groups and so on until every living thing has a distinct name due to their distinct characteristics.) The Linnaean taxonomy hierarchy from top to bottom: 1. domain 2. kingdom 3. phylum 4. class 5. order 6. family 7. genus 8. species 9. subspecies (occasionally used) Why is so much of it still in use? The system has been continuously refined over the years with different groups being added when a new discovery is made. Linnaean taxonomy is still in use because the hierarchical system is very efficient in presenting information. For example, the Linnaean classification of humans gives much information about our characteristics: Domain: Eukaryota We are eukaryotes, which means we belong to organisms that are composed of more than one cell. (unlike prokaryotes) Family: Animalia We are animals (as opposed to plants and fungi eukaryotes), which means we have practically all animal features. Phylum: Chordata We are vertebrates, which means we have a spine. (Unlike jellyfish and such) Class: Mammalia We have mammalian features, which included being warm blooded, giving live births and feeding on milk. Order: Primates We have primate features, five fingers, non-specific teeth, binocular vision etc. Family: Hominidae Hominid features: no tail, omnivorous diet, nails instead of claws etc. Genus: Homo We are the only modern species of the genus homo. Features include bipedalism. Other living things may have several species within the same genus. Species: Homo sapiens The unique name given to our species with all the features of the above hierarchy. Subspecies: Homo sapiens sapiens Some classify modern humans as this subspecies due to differing classifications of other (extinct) species of the genus homo. Due to efficient manner the information of living organisms is presented, the Linnaean taxonomy will continue to be used.
That has not been counted, only estimated.

Scientific names are determined using a system called binomial nomenclature created by Carl Linnaeus. The name consists of a genus and a species name, with the genus capitalized and both words italicized. The names are usually descriptive, based on the organism's characteristics, habitat, or the scientist who discovered them.
If you're really just talking about monkeys then you have to start with old world or new world monkey families such as Cebidae (new world capuchin type) or Callitrichidae (new world tamarans and marmosets) or Cercopithidae (old world monkeys) then they break down further from there.
No one knows what humans will look when they become a new species. It will depend on the type of species that humans evolve into that will determine what they look like.
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.
The common name is human, and the scientific name you answered yourself; Homo sapiens
Two million years ago marks the beginning of the Pleistocene epoch, characterized by fluctuating global temperatures and the evolution of early humans such as Homo habilis and Homo erectus. It was a time of significant geological and biological changes, including the emergence of new species and adaptations in response to environmental challenges.
There were many species that were referred to as "cave men." It's hard to know what caused the extinctions of most of them. However, one species, Homo neandarthalis, appears to have disappeared about 30,000 years ago, which is the same time that modern humans, Homo sapiens, entered Europe. It is believed that humans may have out competed and killed the Neandarthals because we had superior weapons. Also, even members of our species until after 10,000 years ago, are often referred to as "cave men." They did not become extinct; instead, they simply adopted a new lifestyle, which so we don't call them "cave men."
Today there is only one species of Human, however, at one time there were several, including Neanderthal, Homosapien, Sapien, and a few others. Only the homosapiens survived to the modern world.One... but there are many sub-species aprx. 7 billion people on this earth and we are all different in some way

No, humans and Neanderthals shared a common ancestor but evolved separately. DNA analysis suggests that Neanderthals and modern humans interbred, however, the exact extent and impact of this interbreeding is still a topic of study among scientists.
Our species (Homo sapiens) is about 200,000 years old. The neandertal, a species closely related to our own, was about half a million years old. The earliest cave paintings, art work, and evidence of agriculture extend back roughly 20,000 years ago, to the neolithic (new stone age).
Technology such as dating techniques, DNA analysis, and 3D modeling has greatly aided in understanding early humans like Homo habilis. These advancements help in dating artifacts, tracing genetic histories, and reconstructing physical appearances, shedding new light on their behaviors and evolution. Technology allows researchers to analyze data in more detail and from different perspectives, deepening our comprehension of early human species.
Humans can unintentionally disperse species through activities like international travel, trade, and transportation of goods, leading to the introduction of non-native species to new environments. Humans can also deliberately introduce species for agriculture, hunting, or as pets, further impacting ecosystems. Additionally, habitat destruction by humans can disrupt natural dispersal patterns of species.
Since species evolve and evolution is a slow but steady process it's hard to talk about "the first human". There isn't a moment in history where one animal suddenly gives birth to a new kind of species from one generation to the next. There are however small changes which can be considered drastic enough to be named as a new species. The first hominid skeleton, named Lucy, was discovered in 1974 in Ethiopia. They dated her bones to be 3.2 million years old. The first homo sapiens date back from little less than 200,000 years ago. They discovered a 195,000 year old fossil, also in Ethiopia which shows the first traits of skull changes which are considered to be traits of "modern humans". These traits are a rounded skull with projecting chin. Another skeleton found in the Middle Awash Area shows the same traits of these changes. They can be considered to be the "first humans" but they weren't completely like us, just partially, since evolution happens gradually. According to the bible and other religious factors, many people believe that the first humans were created on earth at 4,000 BC, along with every species of animal which was created with them. However, this would mean that humans and dinosaurs must have coexisted. Which has been proven to be false by scientists.
