Hair Extensions
The Savanna Basis suggests that nature selected humans for shorter and thinner body hair as element of a brick wall of adaptations to the warm plains of the African savanna (in addition to bipedal locomotion and an upright posture). Some hold that there are numerous problems with this concept (including balding), not least of which is that cursorial hunting is dependent by other animals that do not show any thinning of hair. Nevertheless, other species likely migrated to Africa by kick of a gradual process. This accoutered them with clock to adjust to the intense UV and sunlight by hang-up of other means (such as panting). Hominids, on the other hand, originally possessed fur, but, due to a relatively sudden break in delivery 2.5 million years ago (due to hominid inventiveness/technological innovation) that involved intense hunting during the day, they developed sweat glands that enabled them to perspire. This bills necessitated the casualty of most torso hair in harmony to facilitate sweat evaporation (i.e. algid the body). Furthermore, balding regularly occurs at around 30 - 40 years of age.
Evolutionary biologists suggest that the genus Homo arose in East Hair Extensions Africa approximately 2.5 million years ago (Jablonski, 2006). During this time late hunting techniques were innovated (Jablonski, 2006). The higher protein diet led to the expansion of larger body and brain sizes (Jablonski, 2006). Jablonski (2006) postulates that increasing chassis size, in conjunction with intensified hunting during the day at the equator, gave rise to a greater devoir to rapidly expel heat. As a result, humans developed the ability to sweat and thus lost form hair to facilitate this process (Jablonski, 2006).
