Homo as a genus of the order Primates is first recorded 1797

Humans are noted for their desire to understand and influence their environment, seeking to explain and manipulate natural phenomena through science, philosophy, mythology, fables, tales, and sagas. This natural curiosity has led to the development of advanced tools and skills, which are passed down culturally; humans are the only animal species known to build fires, cook their food, clothe themselves, and use numerous other technologies.
Humans are a eukaryotic species. Each diploid cell has two sets of 23 chromosomes, each set received from one parent. There are 22 pairs of autosomes and one pair of sex chromosomes. By present estimates, humans have approximately 20,000–25,000 genes. Like other mammals, humans have an XY sex-determination system, so that females have the sex chromosomes XX and males have XY.
