Whereas the australopithecines had a brain that was, on average, cubic centimeters—roughly the size of a chimp's brain— H. To that end, Roland Moll of Philipps University in Marburg, Germany, and his colleagues have shown that the keratins present in human body hair are extremely fragile, which is why these hairs break so easily compared with those of other animals. For an added bonus, wait until the core stage reentry. The outstanding barrier capabilities of our skin arise from the structure and makeup of its outermost layer, the stratum corneum SC of the epidermis.

Their secretions combine to coat hairs with an oily, sometimes foamy, mixture think of the lather a racehorse generates when it runs. Not Entirely Nude However it was that we became naked apes, evolution did leave a few body parts covered. The largest terrestrial mammals—namely, elephants, rhinoceroses and hippopotamuses—also evolved naked skin because they are at constant risk of overheating. Many of these creatures live underground or dwell exclusively in the water. Carnivorous animals therefore need to range farther and wider than their herbivorous counterparts to procure a sufficient amount of food.

Furthermore, mammals can use their fur in social displays to indicate aggression or agitation: Early human ancestors are believed to have had pinkish skin covered with black fur, much as chimpanzees do, so the evolution of permanently dark skin was presumably a requisite evolutionary follow-up to the loss of our sun-shielding body hair.

Many research groups are now investigating how epidermal stem cell niches are established and maintained, and this work should clarify what directs the fate of embryonic epidermal cells and how more of these cells become eccrine sweat glands in humans. Naked cat walks. Early in development, groups of epidermal stem cells in specific locations interact with cells of the underlying dermis, and genetically driven chemical signals within these niches direct the differentiation of the stem cells into hair follicles, eccrine glands, apocrine glands, sebaceous glands or plain epidermis.
