Heritable variation is the variation in characteristics caused by genetic factors.
mutation brings about variation which is the basis of evolution and the two types of variation are heritable and non-heritable
Intraspecific variation
Religious scriptures about Darwinian evolution by variation and selection? None that I am aware of.

Reproductive variation is central to evolution. All else in evolutionary theory follows directly or indirectly from the fact that organisms reproduce with variation.
The environment is the ' natural selector ' of all variation. This is evolution.
