Classics in #evolutionarybiology do not make you optimistic about human nature. From Charles Darwin’s Descent of Man onwards, there is a fundamental understanding among biologists that organisms, especially humans, evolved to maximise self-interest. We, or rather our genes, act to promote our own success or that of our family. More recently, however, anthropologists and psychologists have pushed back against this pessimistic view. Is the #selfishgene concept wrong?

Cryptic fitness consequences of a selfish X chromosome

Another nail in the coffin of "biological determinism":

"Study finds cell memory can be more like a dimmer dial than an on/off switch"

<💬>
The researchers carried out experiments in which they set the expression of a single gene at different levels in different cells. While conventional wisdom would assume the gene should eventually switch on or off, the researchers found that the gene’s original expression persisted: Cells whose gene expression was set along a spectrum between on and off remained in this in-between state.

The results suggest that epigenetic memory — the process by which cells retain gene expression and “remember” their identity — is not binary but instead analog, which allows for a spectrum of gene expression and associated cell identities.

Study finds cell memory can be more like a dimmer dial than an on/off switch

In a new study, MIT engineers report that a cell’s memory is set not by on/off switching but through a more graded, dimmer-like dial of gene expression.

I read The Selfish Gene as a teenager.

Some found it cold. Others found it reductive.

I found it honest.

It offered me the beginnings of an algorithm for what objective compassion would actually have to look like in a mechanistic world.

Not sentiment masquerading as ethics, but a model of cooperation that emerges from elements maintaining their own well-being, growth, and perpetuation of identity.

The selfish gene theory, popularized by Richard Dawkins, is not the only way to explain evolution. A new book by biologist David Sloan Wilson argues that natural selection operates at multiple levels, from genes to groups, and that cooperation is as important as competition. The book also challenges some of the cultural and political implications of the selfish gene idea, and offers a more nuanced and holistic view of life. #evolution #selfishgene #bookbite https://nautil.us/the-case-against-the-selfish-gene-358473/
The Case Against the Selfish Gene

Richard Dawkins’ hypothesis buries a crucial part of life’s story.

Yes, that rings true. And don't they just hate it when you try to slow things down and think it through, or point out to them that what they just said isn't quite right.

And a problem with my reply is that I said "they" when arguably I should have said "we". So what does that say about me?

Well, this wasn't about me, so I'll leave that thought on hold and return to your idea. There must be an evolutionary advantage to BOTH working it out thoroughly for accuracy AND simplifying for speed and convenience. Either can get eaten by the tiger, depending in the circumstances. And it is in the interests of the species to maintain diversity so that, in any given scenario, a decent number survive to reproduce.

Nice! I hope I understood your toot. I like the cascade it started over here!

#SelfishGene

A debate between Richard Dawkins and Denis Noble: The Selfish Gene
https://iai.tv/video/the-gene-machine

Dawkins' #SelfishGene has been a hugely influential theory for #evolutionary #biology, but critics argue that it is too simplistic, ignoring group selection and the effect of the environment. A debate has emerged over whether the Selfish Gene reduces humans to machines and is hindering medical research: ultimately, it remains to be seen whether it is a valid and accurate account of who we are.

Dawkins re-examined

Dawkins' Selfish Gene has been hugely influential, both within evolutionary biology and in the wider public sphere. It's a beautifully simple story: genes and not organisms drive evolutionary change. But critics argue the story is simplistic. The effect of a gene is not always the same and as is dependent on its host and the cell environment. DNA does not come neatly divided into individual genes. And in 2010 the renowned biologist EO Wilson and others revived the case for group selection. Some are now arguing that the Selfish Gene paradigm is holding back medical research.Is it time to move on and acknowledge that Dawkins' theory is not the whole story? Might his theory be making a fundamental mistake in reducing humans to machines? Or does the Selfish Gene remain a remarkably powerful and accurate account of who we are?
