Document Summary
No clear genetic boundaries (gradients of traits, interbreeding) Any 2 humans only differs about 0. 1% in their dna regardless of their. Only about 10-15% of all known genetic variation (within that 0. 1%) represents adaptations to environments that results in skin colors, eye color, etc. The variations are recent, and superficial (related to climate adaptations) No clear genetic boundaries - no way to decide where does white ends and brown begins. We don"t inherit our genetic materials in "bundles" Homo sapien (human) is too young, we haven"t evolved enough to have distinct genetic differences. All our differences are superficial adaptations to environments etc. Sickle cell disease - a genetic disease (that effects african americans) You get it if you inherit from both parents. Found in central and western africa (primarily along the coast), coast of north africa, coast of the mediterranean.
