Professor Rosenstein's discovery also revealed the attitudes prehistoric women had toward shorter men and others deemed unsuitable for mating.
"The average female during this period would mate with the tallest male, sometimes with several of the tallest males all at once. These encounters could last for hours, even days" he wrote.
"But any short or undesirable male who dared approach a female would become the victim of a group attack that would begin with a protest of sorts, followed by the male being killed and fed to wild animals," he added.
