Massive and extensive scientific research does not support the theory of evolution but creation

Each species has its own specific mitochondrial sequence and other members of the same species are identical or tightly similar


Excerpts: "Researchers report important new insights into evolution following a study of mitochondrial DNA from about 5 million specimens covering about 100,000 animal species."

"In genetic diversity terms, Earth's 7.6 billion humans are anything but special in the animal kingdom. The tiny average genetic difference in mitochondrial sequences between any two individual people on the planet is about the same as the average genetic difference between a pair of the world's house sparrows, pigeons or robins. The typical difference within a species, including humans, is 0.1% or 1 in 1,000 of the "letters" that make up a DNA sequence.

Genetic variation - the average difference in mitochondria DNA between two individuals of the same species - does not increase with population size.

The mass of evidence supports the hypothesis that most species, be it a bird or a moth or a fish, like modern humans, arose recently and have not had time to develop a lot of genetic diversity. The 0.1% average genetic diversity within humanity today corresponds to the divergence of modern humans as a distinct species about 100,000 - 200,000 years ago - not very long in evolutionary terms. The same is likely true of over 90% of species on Earth today.
Genetically the world "is not a blurry place." Each species has its own specific mitochondrial sequence and other members of the same species are identical or tightly similar. The research shows that species are "islands in sequence space" with few intermediate "stepping stones" surviving the evolutionary process.

The new study, "Why should mitochondria define species?" (online at http://bit.ly/2LnPK1g) relies largely on the accumulation of more than 5 million mitochondrial barcodes from more than 100,000 animal species, assembled by scientists worldwide over the past 15 years in the open access GenBank database maintained by the US National Center for Biotechnology Information.

"Experts have interpreted low genetic variation among living humans as a result of our recent expansion from a small population in which a sequence from one mother became the ancestor for all modern human mitochondrial sequences," says Dr. Thaler.

"Our paper strengthens the argument that the low variation in the mitochondrial DNA of modern humans also explains the similar low variation found in over 90% of living animal species - we all likely originated by similar processes and most animal species are likely young."

"Is genetic diversity related to the size of the population?" asks Dr. Stoeckle. "The answer is no. The mitochondrial diversity within 7.6 billion humans or 500 million house sparrows or 100,000 sandpipers from around the world is about the same."

"Scholars have previously argued that 99% of all animal species that ever lived are now extinct. Our work suggests that most species of animals alive today are like humans, descendants of ancestors who emerged from small populations possibly with near-extinction events within the last few hundred thousand years."

Another intriguing insight from the study, says Mr. Ausubel, is that "genetically, the world is not a blurry place. It is hard to find 'intermediates' - the evolutionary stepping stones between species. The intermediates disappear." "

Dr. Thaler notes: "Darwin struggled to understand the absence of intermediates and his questions remain fruitful."


Summary and conclusions:
  • The research is very extensive; scientists analyzed mitochondrial DNA from about 5 million specimens covering about 100,000 animal species.
  • Species mean 'a group of species' = kind
  • The typical difference within a species (kind) is 0.1% or 1 in 1,000 of the "letters" that make up a DNA sequence. This same pattern is true within humans too.
  • Species (kinds) are "islands in sequence space" - Intermediates disappear.
  • Darwin struggled to understand the absence of intermediates and his questions remain fruitful.
  • Each species has its own specific mitochondrial sequence and other members of the same species (kind) are identical or tightly similar
  • Most animals, like humans, come from a small population that has survived a major catastrophe.
  • According to researchers, about 90% of world's organisms originated at the same time about 100,000 to 200,000 years ago.

    But please note that researchers have used theoretical mtDNA mutation clocks based on phylogenetic analyses. Observed mtDNA mutation rates are roughly twenty-fold higher than estimates derived from phylogenetic analyses. This leads to a conclusion that ~90% of world's organisms originated at the same time about 4500 - 10,000 years ago. This large and extensive study perfectly supports biblical creation and worldwide flood, organismal variation in kinds and mtDNA degradation. Just like DNA mutations, mtDNA mutations never result in any kind of evolution.
