Evolution 101 Common Ancestor

evolution 101The Evolution 101 Common Ancestor website, produced by the University of California, argues that “the central idea of biological evolution is that all life on Earth shares a common ancestor.”

This idea dates back to Charles Darwin’s grandfather, Erasmus Darwin (1731-1802). He proposed that “all warm-blooded animals have arisen from one living filament,” which is a common ancestor.

In their book Tree Thinking (2013), David Baum of the University of Wisconsin, along with Stacy Smith of the University of Colorado, attempts to build on this Darwinian argument. “This means,” they argue, “that evidence of common ancestry is also evidence for evolution.”

Genetics of Darwin’s Finches

Darwin's FinchesThe finches Charles Darwin encountered on the Galapagos Islands have served as one of the most enduring examples of evolution throughout the twentieth century.

As  Darwin explains in The Origin of Species, “one [finch] species had been taken and modified [changed] for different ends” – the essence of natural selection.

However, in the nineteenth century. The technology to scientifically validate these changes in the genetics of Darwin’s finches was inconceivable.

Genetic Origins Uncoding Evolution

Zagrovic, Bojan IIThe genetic code is the universal language of life, from the first microbe to man. Searching for the origins of the first genetic code mystery, however, is akin to deciphering the evolution of life.

Over the past two years, the research team of Bojan Žagrović (pictured) at the Max F. Perutz Laboratories of the University of Vienna has been searching for a natural mechanism driving the genesis of the original genetic code − a longstanding challenge of the evolution industry.

Since the interactions between genetic material (nucleobases, DNA, and mRNA) and amino acids produce the workhorse molecules of life–proteins, Žagrović’s research team has been focusing on understanding what might have been the initial natural physicochemical mechanisms producing the original genetic code.

The European Eel Challenge

European EelThe European eel illustrates exactly why Charles Darwin’s theory of evolution has continued to be on the wrong side of science. Darwin once argued that.

“By the theory of natural selection, all living species have been connected… So that the number of intermediate and transitional links, between all living and extinct species, must have been inconceivably great.”

Since the publication of The Origin of Species in 1859, Darwin’s “inconceivably great” number of evolutionary transitional links in the fossil record over the past 150 years remains missing despite the vast discovery of fossils.

Conflicting Conclusions on Speciation

Songbird II Two new research studies, one on Himalayan songbirds and one on Brazilian ants, arrive at conflicting conclusions on speciation. The songbird research study was published in the prestigious British journal Nature, while the ant research study was published in the American journal Current Biology.

Trevor D. Price of the University of Chicago led the songbird study, and Christian Rabeling of the University of Rochester led the Brazilian ant study, both highly respected international teams.

While the findings in the Himalayan songbird study support Charles Darwin’s speciation theory of geographical isolation, the Brazilian ant’s findings undermine his theory. Speciation, an evolutionary term intended to explain how new species might have developed from existing species, is in trouble once again.
