Skin colour is one such characteristic and is presumed to have lightened in colour as our ancestors gradually migrated away from the equator thereby requiring less protection from UV damage by way of melanin and improved bodily vitamin D production from their reduced sun exposure.

Our skin and eye colour range is another result of evolutionary adaptations to different environmental conditions.Our appendix is another vestige from when a diet higher in plant material required the appropriate gut bacteria to fully digest it. Our progression to an omnivorous diet saw it become largely redundant.
