Line 8:
Line 8: − ==DNA fingerprinting== − DNA can help police track down criminals if an attacker leaves something like hair or blood at a crime scene. Everybody’s DNA is unique unless they are identical twins, and the genetic ‘fingerprint’ of this material can be enough to confirm if a suspect was at the scene. − Genetic fingerprinting can also show if somebody is closely related to somebody else. Archaeologists used samples from living relatives to identify whether bodies found buried in a forest in [[Russia]] were the remains of the [[Tsar]] and his family, killed during the 1919 [[Russian revolution]]. − − As well as showing how different we all are, DNA shows how much we are all the same. Only one small part of one chromosome distinguishes a boy from a girl. Genes give us different colored eyes, hair and skin, but 99.5% of any human's DNA is in the same order as everybody else’s. − − Every living thing on earth has DNA that uses the same basic chemicals as human DNA, but because their chemicals are in a different order, the DNA of a worm or a tree encodes for different proteins, and those proteins make different cells. Evolutionists believe that all these cells developed from the first single-cell creatures formed three thousand million years ago, evolving gradually into new species to adapt to their environment. Creationists believe that God created living things as distinct [[baraminology|"kinds"]], and point to [[information]] theory to show that the information on the DNA could not have arisen by chance.
