"I have mainly made my case by citing the complex DNA encoding and cellular mechanisms whose origins have never been explained and in many ways, defy scientific explaination.
DNA coding seems to support an evolutionary path of life. For example, genes associated with certain body features on an organism dont "disappear" in subsequent derived species. The genes are retained on the chromosomes but are non functioning. They become "fossil genes".
How about the gene compliment of humans v chimpanzees(and all great apes). The genomes are practically the same except that there is one big visible difference.A human genome has one less chromosome than that of the great apes. Chimps and gorillas have 24 chromosomes and humans have 23.In 1982 Yunis and Prakash published THE LANDMARK paper on the evolution of humans from apes from a genetic viewpoint. They looked at this chromosomal difference and found that every human chromosome has a matching chromosome on chimps and apes , except for one, human chromosome 2 , which"sorta" matches 2 different chromosomes in the great apes.(At that time, they couldnt analyze the makeup of telomeres or centromeres with any equipment then available.)
The two ape chromosomes that match human chromosome 2 , are chimp chromosome 2A and 2B. Their structures and all their DNA align them perfectly with human chromosome 2.
The analyses of these facts are that, if humans and chimps shared a "common ancestor" human chromosome 2 probably was formed by the fusion of 2A and 2B after human lines split from the one that would arrive as a modern chimp. Or , fission of chimp chromosome 2a and 2B may have resulted from fission of an ancestral chromosome after the chimp and human lines split, OR, as some Creationists had tried to assert, These two lines may have originated independently with no evolutionary relationship, just a mere illusion of it.
9 years after Prakash and Yuris paper , another team cleared up the evidence. The showed that the TELOMERES of the apes chromosomes 2A and 2B are found in the deqd center of human chromosome 2All the DNA of the 158 repeat alleles that define the TELOMERES of the apes are found and aligned perfectly in a humans chromosome 2. The entire structure of a chimps chromosmes 2A ansd 2B are hung together just like and extension ladder where the rungs of the ladder re made up prfectly of the two "horter ladders " of an apes chromosomes 2A and 2B. The telomeres of the two ape chromosomes are fused "head to head" to form a human chomosome 2 . The team (from Yale -boola boola) produced a "MAP" of the fusion point and the entire sequences of DNA of both the ape and the human. The centromeres of the ape and hiuman chromosomes align also align except for one centromere which ,Avarello called an alphoid sequence,it is sorta retained in the human genome as a "fossil remnant site" where a torn up centromere of Chimp chromosome 2B remains.
Howd this happen you ask?? I think a reasonable conclusion is evolution clear and unmistakable. The chromosomal fusion in human no. 2 happened AFTER the lineage leading to humans diverged for the lineage that arrived at the great apes. This stuff is 35 and 25 years old but seems to be totally ignored by all Creationist/ID readers
