Molecular clocks are calibrated in accord with dates assigned to fossils and the mutation rates of DNA. Since evolution of new life forms supposedly occurs by accumulating favorable mutations, knowing the mutation rate is essential to evolutionary time estimates.
The first direct measurement of human mutation rates ever done contains surprises which call molecular clock assumptions into question and prompt some re-thinking of our genetic understanding. Analysis of data from two families in the “1000 Genomes Project” database suggests that humans mutate much more slowly than predicted.
Dating of fossils requires certain unverifiable assumptions, as does dating of genetic events by any sort of “molecular clock.” Evolutionists have trouble seeing how mutations can produce variety so “quickly” and are much happier when a couple of million years can be added to the available time.
Molecular clock dates were too old to suit the evolutionary story.
Mitochondrial Eve finally meets Y-chromosome Adam (sort of).
Genomic study suggests the presence of ancient anatomically modern humans all over Africa.
Researchers at University of Texas–Arlington have found “old” virus fragments from the same family as modern Hepatitis B virus in the genomes of modern songbirds.
A new study of the Simian Immunodeficiency Virus (SIV), a virus infecting “almost all African monkeys” but not sickening them, has led to speculation about how long the virus has been around in its present form.
Geneticists are increasingly relying on the technique of comparing genomes in the search for dates, as opposed to the old method of digging up fossil bones.
Answers in Genesis is an apologetics ministry, dedicated to helping Christians defend their faith and proclaim the gospel of Jesus Christ effectively. We focus on providing answers to questions about the Bible—particularly the book of Genesis—regarding key issues such as creation, evolution, science, and the age of the earth.
