智人（学名：Homo sapiens，意为“有智慧的人类”）是脊椎动物亚门哺乳纲灵长目人科人属唯一现存的物种，在演化生物学上分早期智人和晚期智人两个演化阶段，从人类文明发展的角度，早期智人又可称古人，晚期智人则为新人，此外还有已灭绝的亚种长者智人。 智人的正模标本是卡尔·林奈，由他自己在第10版《自然系统》中指定。该标本（遗体）现保存（安葬）于瑞典乌普萨拉大教堂。

Everything we know about the Human
Typical adult figures. Where a value is an estimate rather than a measurement, it says so.

MEAN velocity over the full 100 m: 100/9.58 = 10.44 m/s. Peak instantaneous velocity during that run was higher. An elite sprinter, not a typical adult.

By sex
- Male909 NWaltimo & Kononen 1995, Acta Odontol Scand 53(4):254MEASURED maximum voluntary bite at the MOLAR, n=56 men, SD 177 N. Incisal bite in the same study is 382 N -- about half -- which is why bite position has to travel with the number. Finite-element modelling of a human skull gives a higher 1109-1317 N at the second molar (Wroe et al. 2010, Proc R Soc B 277:3579): models estimate the physiological ceiling, voluntary clenching does not reach it.
- Female777 NWaltimo & Kononen 1995, Acta Odontol Scand 53(4):254MEASURED maximum voluntary bite at the MOLAR, n=73 women, SD 168 N. Incisal bite in the same study is 325 N.
