how we became an invasive species

invasivesBiocultural adaptation: the pattern of human evolution in which the effects of natural selection are altered by cultural inventions.

Culture can alter the direction of evolution by creating non-biological adaptations to environmental stresses (e.g., clothing, controlled fire, agriculture).

This potentially reduces the need to either remain within habitat boundaries or evolve genetic responses to natural limits. This has meant that we have been able to remain essentially tropical animals biologically while colonizing outside our natural habitat into non-tropical regions.
