For decades scientists have been engaging each other in the nature vs. nurture debate. The nature vs. nurture debate raises the question about whether human development is mostly based on behaviors which are inherited or those which originated from environmental influences.

My sister’s two children, Taylor and Abigail are biological siblings who inherited their green eyes from their mother and their straight teeth from their father, but that is where their similarities end.
