Short answers, pulled from the story.
What chromosomes determine that a human is male?
A man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father, producing a male karyotype, XY. The SRY gene on the Y chromosome triggers the development of the testes, which govern the rest of male sex differentiation.
Who is the earliest known recorded name of a man?
The earliest known recorded name of a man may be Kushim, who would have lived between 3400 and 3000 BC in the Sumerian city of Uruk, though the name may have been a title. The earliest confirmed names are Gal-Sal and his two slaves, En-pap X and Sukkalgir, from around 3100 BC.
Why do men live shorter lives than women?
Women live longer than men in all countries and across all age groups for which reliable records exist. Men face higher mortality from armed conflict, where a study of 13 countries from 1955 to 2002 found 81% of violent war deaths were male, as well as from dangerous occupations, with ten times as many men as women dying on the job in the United States in 2020.
What are the secondary sex characteristics of men?
Secondary sex characteristics specific to men include broadened shoulders, increased body hair, an enlarged larynx known as the Adam's apple, and a voice significantly deeper than that of a child or a woman. On average men are taller than women by about 10% and carry greater lean and bone mass and lower fat mass.
Where does the word man come from?

What is the origin of the Mars symbol for men?
The Mars symbol that represents the male sex was first used to denote sex by Carl Linnaeus in 1751 and is identical to the planetary symbol of Mars.
