“We humans have many vestigial features proving that we evolved,” argues Jerry A. Coyne, Ph.D. (pictured left), biology professor at the University of Chicago. Coyne is the author of the book Why Evolution is True. Vestiges are biological features thought to be evolution relics. Scientific evidence, however, is critical; are evolution vestiges fact, or fiction?
Aristotle (384–322 BC) originated the vestiges theory. Even though WIKIPEDIA considers the theory as “controversial and not without dispute,” the carte blanche use of vestiges continues as supporting evidence for the popular “evolution is true” argument.
Recent advances in biotechnology, however, are challenging the scientific validity of the evolution vestiges theory.
New high-resolution CT scans of the Taung Child skull (pictured left) by an international research team led by Ralph L. Holloway of Columbia University in New York raise renewed questions about the institute’s inane Smithsonian evolution storytelling practices.
Discovered in 1924 in South Africa, models of the skull have long since been duplicated for natural history museums worldwide, including the Smithsonian, as evidence for human evolution. Found near Taung, South Africa, the lynchpin skull was tagged with the common name of Taung Child because of the fossil’s estimated age of 3 years. It was later named Australopithecus africanus, meaning the “southern ape from Africa.” However, Hollow’s new high-resolution CT scan images undermine the long-held pre-Homo fossil status of the skull.
For more than two decades, international teams of paleoanthropologists have been discovering human-like fossils from a medieval archaeological site in the former Soviet Republic of Georgia known as Dmanisi.
A new human Georgian skull fuels the dilemma further. In 1991, David Lordkipanidze of the Georgian National Museum in Tbilisi discovered the first four human-like fossils.
Increased archaeological interest in this Georgian site began in 1936 following the discovery of ancient and medieval artifacts.
Charles Darwin started the debate over where humans originated. In the 19th century, most evolution scientists believed humans originated in Asia–the Out-of-Asia model. In the 6th Edition of The Origin of Species (1872), while Darwin mentions “humans” ten times, he never discusses the origin of humans.
Exploring human evolution via DNA was essential for twentieth-century evolution scientists. Charles Darwin, however, in The Origin of Species, never used the terms genetics, genetic, and genes until 1872, following the publication of the pea plantinheritance report of Gregor Mendel in 1866.
In his sixth edition, Darwin used the term “genetic” twice, but only to express a genealogical idea, not as a molecular term. In the words of American evolutionary biologist Richard Lewontin,
Darwin, Then and Now, the Most Amazing Story in the History of Science, chronicles Darwin's life, how he developed his hypothesis, specifically what he said, and what scientists have discovered since the publication of The Origin of Species in 1859.
The book traces the rise and fall of evolution's popularity as a scientifically valid theory. With over 1,000 references from Darwin and scientists, Darwin Then and Now retraces developments in the most amazing story in the history of science.
Darwin Then and Now is an educational resource focusing on understanding the intersection of evolution and science to develop basic skills for analyzing and assessing the theory of biological evolution.
