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 evolution. The amount of difference in DNA is a test of the difference between one species and another â and thus how closely or distantly related they are.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.
Conversely, when sinkholes become plugged, they. can cause flooding by capturing surface-water flow and can create. new wetlands, ponds, and lakes. Most of Florida is prone to sinkhole formation because it is under-. lain by thick carbonate deposits that are susceptible to dissolution. by circulating ground water. Floridaâs principal source of freshwater, ground water, moves into and out of storage in the carbonate aqui-.
Earthquakes, while possible, are quite rare. Our major geologic threats are sinkholes. Florida has the largest concentration of sinkholes in the United States. According to the Florida Geological Survey (FGS), sinkholes cause millions of dollars in damage each year to public property, highways and private homes.
