Question John,
What was the life expectancy of Homo Habilis, Homo Erectus, and early Homo Sapiens? Is 18 to 20 years about right, with the oldest age around 40?
Thanks,
Tom
Answer Tom
Your figures is about right for maximum life expectancies. Individuals in their 40s are extremely rare. Some scholars place the age of the "old man" of La Chapelle aux Saints in its mid-30s. Be aware, though that once individuals are skeletally mature (ca. 18 years) estimates of age are based on wear and tear on the skeleton, and this can vary widely among individuals based on subsistence adaptation, parasite load and other factors.
Cheers
