What Is Mankind?
The sexually dimorphic human
Humans are sexually dimorphic. Humans develop sex characteristics at puberty. At the age of 50, women are infertile and capable of having babies.
Challenges to predominant gender norms have recurred in many societies, and the nature of male and female gender roles has varied historically. Humans have used fire and other forms of heat to cook and prepare food since the time of H. erectus, they are omnivorous and capable of consuming a wide variety of plant and animal material. They can survive for up to eight weeks without food and water.
Humans sleep on average seven to nine hours per day. Childbirth is dangerous and can lead to death. The mother and father provide care for their children who are helpless at birth.
Is mankind great?
It is wrong for OP to say that mankind are great. Some people won't like it, but it's fine with others. It's a collective word, which can take either plurality according to context.
Evolutionary Genetics of Primitive Cataracters
The question of whether there was a gene flow between modern humans and Neanderthals has been solved with the use of genetic evidence. It is possible to reconstruct a genetic tree incorporating the entire human species since the last shared ancestor by comparing parts of the genome that are not under natural selection and which accumulate mutations at a fairly steady rate. Human evolutionary genetics studies how one human genome differs from the other, the evolutionary past that gave rise to it, and its current effects.
There are implications and applications for differences between genomes. Data from genetics can provide insight into human evolution. The primate's evolutionary history can be traced back 65 million years.
One of the oldest primate-like mammal species, the Archicebus, came from China. The tropical conditions of the Paleocene and Eocene made for a widespread existence of similar primate. The many kinds of arboreally adapted primitive catarrhines from East Africa suggest a long history of prior diversification.
The earliest Old World monkey is attributed to the fossils at 20 million years ago. The ape genera thought to be in the ape line up to 13 million years ago are Proconsul, Dendropithecus, Limnopithecus, and Nacholapithecus. The recent evolution of light skin and blond hair in some populations is attributed to differences in climate.

Art and the Future
People are optimistic about their future because of art. Art can be used to inspire people to achieve great things. Art can be a way of communication between people, to focus on common issues. The best form of creativity is music.
The buttock in man
The buttock is different in man than in any other animal. The upper part of the thigh is what goes by that name in other creatures. The two epigraphs give partial answers to the questions.
Where is human consciousness? It is from the extensive tool use that it is possible to erect. What is it that it does?
It is a set of simulations. The second class is an automatic one that emerges with the increasing order of tools. They can be very complex and include a machine A that produces machine B which produces machine C which produces screws.
