Embryology plays a critical role in Charles Darwin’s theory of evolution. The “leading facts in embryology … [were] second to none in importance,” he argued in The Origin of Species.
Illustrations of embryos by Ernst Haeckel, a German biologist, influenced Darwin. Haeckel’s drawings portray embryos repeating the steps of evolution, known as the “ontogeny recapitulates phylogeny” theory.
It is thought that genes drive evolution through natural selection. Since turtles have a unique body plan, studying the turtle genome during embryonic development is expected to give insight into their origin.
Natural selection emerged as the cornerstone law of evolution following the publication of The Origin in 1859. “I do believe,” Darwin argued, “natural selection acts slowly by accumulating slight, successive, favorable variations.”
Natural selection, the tenet of Darwin’s theory, when viewed through the lens of twenty-first-century technologies, increasingly faces scientific challenges.
The long-awaited analysis of one of the most influential lobed-finned fish in evolution history, the coelacanth genome (pictured left), was published last week by Chris T. Amemiya (pictured right below) of the University of Washington and Jessica Alföldi from MIT and Harvard in the prestigious journal Nature.
The coelacanth plays a crucial and colorful role in the history of evolution.
A research team led by Michael Blaber of Florida State University College of Medicine recently reported a solution to a problem with the “protein-first,” also known as the protein self-assembly origin of life theory. The issue involves protein folding.
Biologically active proteins are only functional when folded into specific molecular structures.
Proteins’ ability to fold into specific structures is essential to performing cellular functions. While the team’s approach aligns with Charles Darwin’s theory, the protein self-assembly origin of life competes with the popular “RNA-first” origin of life theory.
“The origin of life on Earth is a scientific problem,” according to WIKIPEDIA, “which is not yet solved. There are many ideas but few clear facts.”
In 2013, Princeton University hosted an international Origin of Life conference to address this issue.
In the nineteenth century, the “spontaneous generation” theory had long been the natural explanation for the origin of life, starting in Greek philosophy. Even Charles Darwin, centuries later, endorsed the theory in The Origin of Species (1859).
Origin of life researchers collected “new insights” from a new paper entitled “The origin of membrane biogenetics,” published in the December issue of the journal Cell. The media elevated the hype into an origin-of-life sea saga spectacle.
The journal Nature covered the paper in an article entitled “How life emerged from deep-sea rocks” by Ed Yong. The subtitle. “The origin of ion-pumping proteins could explain how life began in and escaped from undersea thermal vents,” seemed to seal the deal.
Charles Darwin‘s story of how the giraffe got its long neck is one of the most popular and widely-told stories in the history of evolution. At the center of the giraffe evolution story is the African okapi (pictured left).
The story begins with Darwin speculating on a transitional link. In The Origin of Species, Darwin wrote –
“It seems to me almost certain that an ordinary hoofed quadruped might be converted into a giraffe.”
Africa’s majestically bizarre leaf-eating giraffe once served as an elite status symbol. Even from early civilizations, images of the giraffe are etched and sketched into the rock all over Africa. Puzzling over how the giraffe got its long neck and gentle behavior, the giraffe was the prize of Kings.
In 46 BC, Julius Caesar brought the first giraffe into Europe. Seeming to blend the characteristics of the camel and leopard, the Romans named the giraffe a “cameleopard.” Caesar presented giraffes to lions in Roman arenas to shred and shock audiences.
Life originated in “a warm little pond,” Charles Darwinwrote to Joseph J. Hooker, the founder of geographical botany within Darwin’s circle of colleagues. How, where, and when the first species got started, however, completely escaped Darwin.
In contemplating the origin of life dilemma, Darwin noted in his autobiography –
“The mystery of the beginning of all things is insoluble by us, and I, for one, must be content to remain an agnostic.”
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.
