After watching this, your brain will not be the same - Lara Boyd - TEDxVancouver

Tted encouragement from her parents, Jablonski began her exploration into the world of science when she was quite young. She recalls exploring the nature around her home, digging for fossils near creeks and trees.

She instantly decided that she wanted to pursue the study of human evolution, dismissing her parents' desire for her to attend medical school. Honoris Causa from Stellenbosch University in During these years, Nina began her research on the evolution of human bipedalism and skin color.

Additionally, Jablonski was inspired to begin her research on the natural history of human skin during her time in Hong Kong. During this nina jablonski ted of nina jablonski ted, she began research on the jablondki of human bipedalism and the evolution of human skin color, which is the foundation of her further research in anthropology.

She thought the study on such topics was valuable for researchers to use the basic tools of comparative and historical biology to deduce what probably happened in the past. During this time, she was also a member of the American Association for the Advancement of Science.

She researches the origin and evolution of the skin and skin pigmentation and the relationships between vitamin D requirements and metabolism in the context of human migration and urbanization. Early in her skin research, she published papers on the connection between neural tube defects and ultraviolet trd which damages folate in the skin, in the controversial and non- peer journal Medical Hypotheses.

Heightened melanin levels occur in populations closer to the equator where UV radiation poses risks of folate damage and depigmentation occurs in areas with low levels of UV radiation so that vitamin-D biosynthesis is not nina jablonski ted. Jablonski connects certain diseases and health risks to people living in areas where their skin color is maladaptive to the nina jablonski ted and people who are living the modern indoors lifestyle[11].


The main diseases she found to be connected with low levels of UV-B exposure are rickets and multiple sclerosis due to inadequate production of vitamin D. Her work has led to significant discoveries including an ape cranium in China, [19] and the first identified chimpanzee fossils. Jablonski's research on the genus Theropithecus nina jablonski ted had significant impact, including the discovery of a near-complete skeleton of T. Her research is central to modern understanding of extinct Theropithecus size, habitat, and diet, [25] much of which is detailed in Theropithecus: The Rise and Fall of a Primate Genus, edited by Jablonski.

She has also written textbook analyses of the fossil record of tarsiers, [26] gibbons, [27] and Cercopithecoidea as a whole. Wheeler hypothesized that there was evolutionary pressure for early hominids to adopt bipedalism because an upright stance with less surface area exposed to sunlight allowed them to forage for longer without overheating. Jablonski's team constructed their own models, which led to the conclusion that thermoregulatory benefits weren't significant enough for nina jablonski ted selection to favor bipedalism.

Student Reflection

Using this information, she concluded that the absence of MAP nina jablonski ted in early primates likely contributed to their extinction in non-tropical latitudes. Jablonski also made connections between goose bumps and brain size, as the ability to regulate body temperature without changes in metabolism seemed to her a necessary adaptation to accommodate the thermal and metabolic sensitivities of larger brains. Inlink traveled to Madagascar where she concluded that lemurs depend on behaviors of sunbathing and huddling to retain heat.
