The Extinction of “Junk DNA”

The term “junk DNA” was introduced in 1972 by evolutionary geneticist Susumu Ohno in the paper entitled “So Much ‘Junk’ in Our Genome” published in the book Evolution of Genetic Systems.

In a landmark book The Language of God (2006), geneticist Francis Collins advanced Ohno’s concept of junk DNA as “powerful support for Darwin‘s theory of evolution” while serving as director of the National Center for Human Genome Research.

Smithsonian Story of Human Evolution, a Scientific Vacuum

“Human evolution is the lengthy process of change by which people originated from apelike ancestors,” according to the Smithsonian Institute presentation entitled “Introduction to Human Evolution”.

The Smithsonian declares that the “[s]cientific evidence show that the physical and behavioral traits shared by all people originated from apelike ancestors and evolved over a period of approximately six million years.” This forward sounding statement, however, is scientifically unsound.

Tracing Human Evolution with DNA

Charles Darwin in The Origin of Species never used the terms genetics, genetic or genes. In the words of American evolutionary biologist Richard Lewontin, “Darwin knew nothing about genes.”

The term “genetics,” was first coined in 1905 by English geneticist William Bateson in a personal letter to colleague Alan Sedgwick. Since then, genetics has emerged to be the center of evolutionary research for more than a century.

This last week, the research article in the journal Science entitled “A High-Coverage Genome Sequence from an Archaic Denisovan Individual” captured media headlines worldwide. Continue Reading

Human Evolution & Toumia

Charles Darwin in The Origin of Species first published in 1859 refers to humans only once: “light will be thrown on the origin of man and his history.” By the time The Descent of Man was published in 1871, Darwin’s intent was clear: advance the concept that “there is no fundamental difference between man and higher animals.”

In developing a theory of human origins, however, amazingly Darwin addresses the problem of the human fossil record evidence only once in The Descent of Man
