DNA. Through news accounts and crime stories, weâre all familiar with the fact that the DNA in our cells reflects each individualâs unique identity and how closely related we are to one another. The same is true for the relationships among organisms.he percentage of genes or DNA that organisms share records their similarities. We share more genes with organisms that are more closely related to us. Humans belong to the biological group known as Primates, and are classified with the great apes, one of the major groups of the primate evolutionary tree.
Range: The range of the five-lined skink corresponds closely with the eastern deciduous forest. The species is found in southwestern New England (currently Vermont and Connecticut and historically in Massachusetts), south to northern Florida, west to Wisconsin, and in eastern parts of Kansas, Oklahoma, and Texas.
Skinks are morphologically distinct from other lizards in their almost cylindrical body with no marked neck, long tail, short or even absent limbs, and scales that are smooth, semicircular and imbricated (overlapping). However, these are not the only lizards that are able to lose their tails as defense. This ability is called autotomy and occurs in most lizards. The only remarkable physiological feature I can think of with respect to skinks is that many are viviparous.
