Consensus on Evolution

Evolution 2.0Public schools require the teaching of evolution as a scientific theory. Amazingly, no science organization in the twenty-first century has successfully developed a scientific consensus on evolution.

Science organizations have a privileged responsibility for developing and publishing a consensus on important issues. While a scientific consensus is not synonymous with absolute truth, it guides the public on what is considered scientifically valid.

Science Organizations

Eighteen science organizations, from the American Association for the Advancement of Science (AAAS) to the American Medical Association (AMA), currently have a consensus statement on climate change. While the consensus on climate change from leading science organizations is silent on a scientific consensus on evolution, the message is clear.

Fate of Darwin’s Finches

GalapagosThe fate of Charles Darwin’s finches is a fascinating saga. Far from England on the equator in the Pacific Ocean lying more than 800 miles off the west coast of Ecuador, the finches Darwin captured on the Galapagos Islands (pictured left), except for one tag, are now missing. As one of the most controversial birds in modern history, the fate of Darwin’s finches belies their current iconic status.

Reaching the Galápagos Islands on September 15, 1835, more than four years after leaving England, the HMS Beagle started preparations to set sail from the island just five weeks later. Darwin had collected many different types of specimens during that time, some weighing up to 500 pounds each. Although typically an avid collector and note-taker, Darwin surprisingly did not record the number of finches collected nor the number loaded onto the ship.

Evolution Vestiges Fact, or Fiction?

Jerry Coyne“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.

Dinosaurs in Unexpected Places

Dinosaur on Sinclair LogoDinosaurs found in unexpected places. In 1933, the Sinclair Oil Corporation sponsored an exhibit at the World’s Fair in Chicago. The Earth’s oil reserves, it was thought, formed during the era of the dinosaurs–the Mesozoic Era.

The exhibit was so popular, a silhouette of a green dinosaur, a Brontosaurus, became Sinclair’s official logo (pictured left). Gaining popularity a few decades later, at the New York World’s Fair in 1964, Sinclair introduced their expanded exhibit, called Dinoland, featuring life-size replicas of nine different dinosaurs, including their signature 27-foot tall and 70-foot long Brontosaurus. Admission was free.

Darwin’s Tree Got Tangled. What Happened?

Within just months of returning from a 5-year voyage on the HMS Beagle, Charles Darwin was quick to start working on a new theory in what he called his “notebooks.” The year was 1837. Etched in a leathery notebook with the letter “B” on the cover, now known as Notebook B, with Darwin’s tree diagram.

Starting with “1” at the tree trunk, the twigs and branches represent relationships between species, like a family tree. Species were indicated with sequential letters; simple enough.

Scientists, however, have become increasingly skeptical of Darwin’s tree metaphor to explain how biology works. “Evolution is trickier, far more intricate, than we had realized,” David Quammen explains in his new book entitled The Tangled Tree (2018). Somehow, Darwin’s tree got tangled. What happened?
