Why do I, or any other human, get sore and cracked heels?
It is there that the search continues for fossils at or near the branching point of the chimpanzee and human lineages from our last common ancestor.
Due to billions of years of evolution, humans share genes with all living organisms.
The bonobo ( humans all show this same amount of difference from gorillas.
A difference of 3.1% distinguishes us and the African apes from the Asian great ape, the orangutan. All of the great apes and humans differ from rhesus monkeys, for example, by about 7% in their DNA.
A comparison of the entire genome, however, indicates that segments of DNA have also been deleted, duplicated over and over, or inserted from one part of the genome into another.
When these differences are counted, there is an additional 4 to 5% distinction between the human and chimpanzee genomes.
"Belt turnover" is commonly cited as a factor that helps to move your foot backwards and thereby makes running on a treadmill easier than running on the road. If so, wouldn't it be felt on any "moving" surface you walk on, such as a train or plane – or even Earth?
Through news accounts and crime stories, we’re all familiar with the fact that the DNA in our cells reflects each individual’s unique identity and how closely related we are to one another.
It also consists of the molecular codes that regulate the output of genes – that is, the timing and degree of protein-making.
DNA shapes how an organism grows up and the physiology of its blood, bone, and brains.
DNA is thus especially important in the study of and another – and thus how closely or distantly related they are.
