Why it's time to lay the selfish gene to rest – David Dobbs – Aeon

Why it's time to lay the selfish gene to rest – David Dobbs – Aeon | Evolution beyond Darwin | Scoop.it
The selfish gene is one of the most successful science metaphors ever invented. Unfortunately it’s wrong

simplistic != scientific

Physiology is rocking the foundations of evolutionary biology

Physiology is rocking the foundations of evolutionary biology | Evolution beyond Darwin | Scoop.it
The 'Modern Synthesis' (Neo-Darwinism) is a mid-twentieth century gene-centric view of evolution, based on random mutations accumulating to produce gradual change through natural selection.

Evolution picks up hitchhikers

Evolution picks up hitchhikers | Evolution beyond Darwin | Scoop.it
In a twist on 'survival of the fittest,' researchers have discovered that evolution is driven not by a single beneficial mutation but rather by a group of mutations, including ones called 'genetic hitchhikers' that are simply along for the ride.
Junaid Akhtar's insight:

"The finding goes against the traditional view of evolution being determined by individual mutations that provide a large fitness advantage by themselves," Desai said. "We found that small groups—which we call cohorts—of mutations were associated with increased survival. No single mutation is driving adaptation. The whole group, which includes hitchhikers, drives adaptation together."

Epigenetic changes accrued over an organism’s lifetime may leave a permanent heritable mark on the genome, through the help of long noncoding RNAs.
Junaid Akhtar's insight:

Another possible blow to the central dogma of biology... in the making.

Letter from Lamarck

I got this letter today from a systems biologist, Dr. Denis Noble of Oxford. It’s a made up letter, but it makes a very relevant point, regarding the similarity between Darwin and Lamarck’s ideas, and how Lamarck has been given such a bad press. Some references might come as a shock to a few neo-Darwinists!

Context crucial when it comes to mutations in genetic evolution, study reports

Context crucial when it comes to mutations in genetic evolution, study reports | Evolution beyond Darwin | Scoop.it
With mutations, it turns out that context can be everything in determining whether or not they are beneficial to their evolutionary fate.
Junaid Akhtar's insight:
whether a given mutation is good or bad is often determined by other mutations associated with it. In other words, genetic evolution is context-dependent.

Boston Review: Is Darwin in the Details? A Debate

The recent reviews in your columns of books by Dennett, Dawkins, and Behe are testimony to the unflagging interest in controversies about evolution. Although such purists as Dennett and Dawkins repeatedly assert that the scientific issues surrounding evolution are basically solved by conventional neo-Darwinism, the ongoing public fascination reveals a deeper wisdom. There are far more unresolved questions than answers about evolutionary processes, and contemporary science continues to provide us with new conceptual possibilities.

Evolutionary developments beyond Darwinian assumptions

Found a great piece, titled Darwin’s Legacy written by Nathalie Gontier that summarizes neatly the development of ideas that challenge and go beyond the simplistic Darwinian/neo-Darwinian assumpyions
