However light is also important since it allows humans to synthesize vitamin D. Therefore if your ancestors lived in an area that receives little light (i.e. For example, long tails in cats could be classified as good, and short tails as bad. The Biology of Skin Color: Black and White. Educator Materials The Biology of Skin Color Short Film September 2015 Page 5 of 15 BACKGROUND “Melanin” is the collective term for a family of pigment molecules found in most organisms, from bacteria to The evolution of race was as simple as the politics of race is complex By Gina Kirchweger. the biology of skin color biointeractive answer key - With regards to achieving a goal a person could just put down on paper what it is you would like. The Biology of Skin Color - NGSS Hub. Anthropologist Dr. Nina Jablonski explains that the variation in skin color that evolved since our human ancestors migrated out of Africa can be explained by the trade-off between protection from UV and the need for some UV absorption for the production of vitamin D. The “Abbreviated Film Guide” provides a short summary of the film, along with key concepts and connections to curriculum standards. However many of us find that will we frequently lose these pieces of paper, or we all don't use a great structure like the SMART targets format. b) People with dark skin living at higher latitudes (less sunny areas) should This is "The Biology of Skin Color — HHMI BioInteractive Video" by Leticia Justo on Vimeo, the home for high quality videos and the people who love… Blond hair has gone in and out of style in Western societies for thousands of years. Differences in skin color among individuals is caused by vastation in pigmentation, which is the result of the genetics. Whenever a species undergoes selection (from evolution), variations can be identified in the genome. She describes how the phenomenon of skin color variation is related to both global distribution of UV intensity and the need for the skin to absorb some UV to produce vitamin D. M & M Genetic Drift Lab Demo . Class site for introductory biology. near the poles) they evolved lighter skin. In ancient Rome, light-haired women dyed their hair dark to stay in vogue. www.BioInteractive.org Published !! Pigment cells create caps around the nucleus to: What organization provided the data that was used to answer her question about the amount of UV. Awesome the biology of skin color biointeractive answer key. The Biology of Skin Color — HHMI BioInteractive Video Descrizione: Penn State University anthropologist Dr. Nina Jablonski explains how different shades of skin color arose as adaptations to the intensity of ultraviolet radiation in different parts of the world. In this film, anthropologist Nina Jablonski walks through the evidence that the different shades of human skin color are evolutionary adaptations to the varying intensity of ultraviolet (UV) radiation in different parts of the world.

An interactive version of the film with embedded pause points and quiz NOTE: Prior to working through the annotated paper, educators may want to assign the HHMI film The Biology of Skin Color, which provides an excellent background for the research presented in the article. In the high ultraviolet (UV) environment of sub-Saharan (or equatorial) Africa, darker skin protects against the damaging effects of UV radiation. Anthropologist Dr. Nina Jablonski explains that the variation in skin color that evolved since our human ancestors migrated out of Africa can be explained by the trade-off between protection from UV and the need for some UV absorption for the production of vitamin D. Is variation in skin color in humans the result of natural selection and adaptation to different environments? This film explores the hypothesis that different tones of skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
