Creationists tend to argue that the 98.5 percent DNA similarity between Humans and Chimps is a myth [9]. They argue this by pointing out several "anomalies" in the comparison such as Chimps having an 11.5% larger genome to Humans [2], and the fact that large portions of both Human and Chimp DNA (1.3 Billion letters) was excluded from the analysis [7,8,9]. Because of this, they say that it is mathematically impossible to get a 98.5% DNA similarity between Humans and Chimps and that the similarity should be at most 89%.
As is known, DNA comparisons are neither simple nor strait forward, and may yield different results according to the method/s used [1]. As explained briefly in the video [7] and in more detail in the paper below [8], they're practical reasons for why Geneticists would exclude large portions of DNA when performing comparisons between Species, and mainly focus the protein coding regions.
Now since Creationists seem to have an issue with the "Evolutionists" methods of measuring DNA similarity between Humans and Chimps, then I have a little test for them. Here we have two Species of Onions, Allium Ursinum and Allium Altyncolicum within the Genus Allium, that are closely related enough to hybridize [5,6] so it shouldn't be difficult to accept that they're related. However, A. Ursinum has a genome size of ~30.81 Billion bp, compared to A. Altyncolicum that has a genome size of ~6.85 Billion bp.
Quote:
"The genome size of 30 Allium species varies from 7 pg (A. altyncolicum, 2n = 4 × = 32) to 31.5 pg (A. ursinum, 2n = 2 × = 14)" [3]
The Onion Test:
By what method/s do we go about measuring the DNA similarity between these two closely related Species of Onions, when one has a genome size that is 4.5 times larger than the other? ...And how do you think your answer would affect your argument against the "Evolutionists" method on the Human/Chimp DNA comparison??
