Memes and baby slings

Baby slings were probably an important technological development that facilitated the expansion of the human brain as our distant ancestors evolved.

Baby slings provided an external womb - in which immature infants could continue their development in reasonable safety and security. The innovation broadly resembles a marsupial's pouch.

Sling manufacturing techniques are culturally-transmitted today - and probably this was always the case.

Baby slings are ancient - the date of their arrival has been traced via the study of lineages of associated lice.

Baby slings probably reduced infant mortality, providing a strong survival advantage to newborns of mothers with the relevant memes. The relaxed selection pressure on cranial size turned out to be a highly significant phenomenon for all memes. Larger brains meant more space for the memes. By providing the technology to facilitate the growth of the human brain, the memes had come across a way of dramatically expanding their own living quarters.
