The Nature vs. Nurture Debate

There's been a debate since not long after the dawn of time as to how much of your culture is learnt through nature, and how much is nurture. (So, genes or how well you're looked after). The balance is unknown, I'm afraid, but here are some cases either side of the debate for you to ponder upon.

Nature
The Jim Twins

Twins called Jim, they separated 4 weeks after birth & were reunited at 39 to study the similarities. So here they are:
 * Both good at maths, both bad at spelling
 * Both enjoy mechanical drawing and carpentry.
 * Both chew their fingernails & Chain Smoke Salem Cigarettes
 * Both get headaches at the same time daily.
 * Both have the same colour, and model chevy car.
 * Both their 1st wives were called Lind, and their 2nd wives Betty.
 * Both have dogs named Toy, and sons named James Allan.
 * Same holiday destinations
 * Almost identical IQ test results.

Nurture
Kamala & Amala "The Wolf Girls"

Raised by a she-wolf, found by an Indian Orphanage in Midnapore, these girls acted just like wild animals, here's some examples:
 * Slept in the day, woke at night, when sleeping curled up in a ball & twitched.
 * Stayed on all fours, enjoyed raw meat, bit & attacked other kids.
 * They were on all fours for so long their tendons and joints had shortened and they couldn't physically stand!
 * They could smell raw meat from a distance.
 * They had an acute sense of sight and hearing.
 * Kamala found it very hard to learn to speak and only learnt a few words.
