I saw this book on another post - and so went and found a copy at a 2nd hand book shop…
Looking forward to lunches at work with a cup of tea and maybe a couple of rainy Sundays at home…

#racism is natural. For millennia homo sapiens eked out an existence on the brink of extinction. Our ancestors lived in small kin groups when everyone who was different was likely to be dangerous and hostile. It served them well. But in today's global society racism is an unhelpful relic of our evolutionary past.

#Evolution gave us brains that allow us to understand that we need to extend "kinship" to all of humanity so that our innate tendency to be racist won't get the better of us.

Use them

Who counts as human? Throughout history, one all too common thread is that groups of people often do not believe that other groups of people are also #human. If we evolved apart so that we were different species, would we recognize our shared humanity? This week I’m offering free copies of my just released novel HUMAN to the fediverse . Just go to bretthodnett.com/FreeHUMAN.htm and use the code ‘fedihuman’.

bretthodnett.comHUMANA remarkable exploration of family, society, and what makes us human, HUMAN will take you from the post-apocalyptic world of the near future, to the two very different societies that emerge 15 million years later, where those few surviving individuals have evolved to become something that we might not fully recognize as human.

EurekAlert!Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesisIn a new study published in Science, researchers from the Model-Based Evolutionary Genomics Unit at the Okinawa Institute of Science and Technology (OIST) and their international collaborators have constructed a detailed timeline for bacterial evolution and oxygen adaptation. Their findings suggest some bacteria could use trace oxygen long before evolving the ability to produce it through photosynthesis.

How will humans #evolve into the future? How might humans evolve if our civilization was lost and the climate was unforgiving for millions of years? Or if two populations of humans were geographically isolated for that long? For this week I'd like to offer #FediHumans a free copy of HUMAN. Visit bretthodnett.com/FreeHUMAN.htm and use the code ‘fedihuman’ to get your free EPUB!

Most people think that #evolution is about dying, but it's not really the full story. It's also about not being born at all. What if people are actually evolving under the extreme pressure of the modern capitalism? The question remains - is humanity under active eugenics and they are selecting us to be their submissive cattle or are we evolving some immunity to the parasites?

Are the few people who do have children under those terrible conditions the ones who treasure their wholesome relationships over career or those who thrive as the slaves? I don't think it's actually being studied in this context. It feels creepy to even put those questions on the table.

Nevertheless, I think that humanity after the full societal collapse will be different from Homo Sapiens. We have reached the limit of that evolutionary plateau. 300k years was a good run. Good Game people! Cheers!

A geological timescale for bacterial #evolution and oxygen adaptation science.org/doi/10.1126/scienc

"the earliest aerobic transition occurred in an ancestor of photosynthetic #cyanobacteria, indicating that the ability to utilize trace amounts of oxygen may have allowed the development of genes central to oxygenic #photosynthesis."

Human defense peptides

Guðmundur H Guðmundsson

Host defense peptide expression improve the epithelial barrier

"Our studies on innate immunity with emphasis on front line defenses have unfolded key components in our innate immunity. Among the components is the sole human cathelicidin containing the host defense peptide LL-37"

It all started with a moth
