New Challenge to Evolution

As a student at Christ’ College in Cambridge (1827-1831), Charles Darwin is reportedly to have given his first microscope by one of his insect collecting friends, John Maurice Herbert. Today, scientists use satellite nanoscopes to study intracellular molecular dynamics and signaling networks between cells.

While loop networks have long been used in architecture, their discovery in biology is credited to Uri Alon of the Weizmann Institute on Science. In 2002, Alon published a by entitled “Network motifs in the transcriptional regulation network of Escherichia coli” in the April edition of the journal Nature Genetics. These newly recognized loop networks, however, present new challenges to evolution.

Darwin Wrong Again

In the first edition of The Origin of Species by Charles Darwin published in 1859, his “geographical distribution” proposal for the emergence of new species was presented in two chapters: 11th and 12th, both entitled “Geographic Distribution,” but Darwin wrong again.

In Darwin’s own words, the emergence of new species was “chiefly grounded on the laws of geographical distribution, that forms now perfectly distinct [species] have descended from a single parent-form,” Geographical distribution and “isolation… is an important element in the modification of species through natural selection.” Until now, however, Darwin’s theory had been largely unchecked and unchallenged.

Imaginative Human Evolution

The origin of the human evolution concept into modern western civilization is largely credited to The Origin of Species by Charles Darwin published in November 1859. Ironically, while arguing for the evolution of new species from existing primitive species, Darwin only addressed the topic of human evolution in one sentence: “Light will be thrown on the origin of man and his history.” 

Darwin’s small spark ignited a raging fire lasting now more than 150 years. Stemming from scientific technological advances, Darwin’s fire is facing the inevitable prospect of being extinguished – estimated to be 60 to 80 pounds, Oreopithecus bambolii is the latest example of imaginative human evolution.

Darwin, Then and Now is a journey through the most amazing story in the history of science - the history of evolution. The book encapsulates who Darwin was, what he said, and what scientists have discovered since the publication of The Origin of Species in 1859.

With over 1,000 references, Darwin Then and Now is a historical chronicle of the rise and fall of the once popular theory of biological evolution.
