Document Summary
Structure vs. function at the molecular level: the woolly mammoth case. Aboriginal tribes used to feed the dogs in their dog sleds mammoth meat. Because they were found frozen in ice, scientists were able to analyze what they ate before they froze, their dna: they had a very selective diet. Mammoths evolved at the same time as all other kinds of elephants. Substitutions in woolly mammoth hemoglobin confer biochemical properties adaptive for cold tolerance. Reconstruction of extinct woolly mammoth haemoglobin protein from 43,000 year old mammoth specimen. Extract dna from mammoth sample mrna functional protein. Its fundamental niche is in both the arctic, and antarctica.
