有些人并未染过头发,其头发为何是红色的?已经灭绝的长毛猛犸,其毛色为何也有明暗之别?科学家最近发现,这些其实都是基因在“作怪”。科学家对取自一头冰冻的西伯利亚猛犸腿骨的古老DNA(脱氧核糖核酸)进行检测后发现,同样的基因不仅造就了红发人,也决定着猛犸的毛色深浅。事实上,这种基因在很大程度上对许多种哺乳动物的毛发颜色都起着决定作用,其中也包括老鼠。尤其值得一提 Some people have not dyed their hair, why the red hair? Extinct woolly mammoths, why the color of their hair is also different? Scientists recently found that these are actually genes in the “mischief.” Scientists tested ancient DNA (DNA) taken from a frozen Siberian woolly mammoth and found that the same gene not only created redheads but also determined the depth of the mammoth coat. In fact, this gene is largely responsible for the hair color of many mammals, including rats. In particular, it is worth mentioning
