The problem is that, due to the Fall, our bodies don’t always do a perfect job replicating our genetic information. Adam and Eve and the Human Genomeīased on the biblical blueprint that we are all descendants of one man and one woman-Adam and Eve-it would seem reasonable to conclude that the genetic information in all humans today ultimately came from Adam and Eve. Evolutionists assume chimps and humans share an evolutionary ancestry and interpret all data according to that assumption. ![]() When DNA sequences are compared more objectively without pre-selecting sequences and filtering the data, the chimp and human genomes are only about 70% similar. However, DNA similarity could just as easily be explained as the result of a common Creator. This recognition site or sequence is generally from 4 to 6 base pairs in length. These restriction enzymes are able to scan along a length of DNA looking for a particular sequence of bases that they recognize. You compare DNA sequences in certain genes, the more similarities their DNA has the more closely related they are.Evolutionists frequently assert that the similarity in DNA sequences provides evidence that all organisms (especially humans and chimps) are descended from a common ancestor. Special enzymes termed restriction enzymes have been discovered in many different bacteria and other single-celled organisms. (2) Another way you can determine the phylogeny of organisms is through DNA comparison. The more similarities the more related they are. The enzymes then digest (chemically separate) the DNA molecule at that sitecalled a 'restriction site'acting like molecular scissors, they cut DNA at a specific sequence of base pairs. You can compare the organisms bone structures or see similar vestigial structures to show that they come from the same ancestor. a double-stranded DNA molecule and slide along the helix until they recognize a specific sequence of base pairs which signals the enzyme to stop sliding. (1) One way you can determine the phylogeny of organisms is through morphology: the study of forms of things. The less differences there are in the amino acids, the more closely they are related. This is because it only has 3 differences in the amino acids with the penguin. The chicken is most closely related to the penguin. There are two types of sequence analysis which are alignment-based (AB) and alignment-free (AF). Since the more fit one has more offspring the frequency of the alleles for the good trait will increase, changing the gene pool. 2 Altmetric Metrics Abstract DNA sequence similarity analysis is necessary for enormous purposes including genome analysis, extracting biological information, finding the evolutionary relationship of species. The ones with the trait have a better fitness and since they survive longer they will have more offspring than that of the creature with the unsuitable trait. Due to natural causes in the environment creatures with the unsuitable trait are killed off and do not survive to reproduce. ![]() Natural selection begins with a species having 2 traits: one suitable for the current environment and one not. ![]() (2) Another way genes change in a gene pool is natural selection. This change can be passed on through the organism's offspring, effectively changing the gene pool. A mutation is when there is a change in a nucleotide sequence. (1) One way genes become changed is through mutation.
