We did not “progress” relative to other apes. When we diverged we “went our separate paths”. But yes, we made progress in the sense that we evolved to live in all of the Earth’s extremes.

As I prepared Sunday School this week, I noticed that it had quite a few posts about Christian Nationalism. That got me thinking about how Ireland in the past functioned very much like a Christian Nationalist state, even if that term wasn’t used at the time. Not fascistic Christian Nationalism like the U.S. fringe wants today, but a soft tacit t…[Read more]

Have a great week everyone and a peaceful and pleasant Thanksgiving.

But cooperative breeding, known as ‘alloparenting’, where individuals other than the biological mother help raise offspring did not start with them. Hominins before erectus already had extended childhoods, reduced canines, increased sociality, and group-based foraging, all of which support cooperative care. Homo ere…

Our lineage split from the other apes circa 5–7 million years ago. That’s when the hominin line begins. Homo erectus appears much later, around 1.9 million years ago and evolved in Africa and yes, they were the first major successful wave to leave Africa. I think they first spread in Eurasia.

Apparently the first human species to make it out of Africa was Homo erectus, ~2 million years ago, and they were the first species to do cooperative breeding, meaning that a woman could have more than one child at once, because she got help in looking after them.  This meant that human children had longer in which to mature.

The human line must…[Read more]

We know that there was a “last common ancestor” (LCA) of chimps/bonobos and humans around 6 million years ago.  I believe the human line got started around 4.5 million years ago.

They are not some sort of “old” humans or “failed humans”. They are modern chimpanzees and specialists in their own ecological niche and with their own evolutionary pressures. Humans didn’t “progress”, we diverged.

That’s true.  But what changed was our environment, when theirs didn’t.

So, where we learned to cop…[Read more]

Simon i think you are guilty of the same mindset as the scientists who first heard about Jane’s discovery.

Not at all, I’ve read a lot of Michael Tomasello and Frans de Waal about what chimps and bonobos can and can’t do, and how they behave.  It was Jane Goodall who paved the way for them.

Surely we grew bigger and more complex brains throughout our evolution, leaving the chimpanzee brain behind a long time ago.

Chimps are not frozen in evolutionary time, stuck at a checkpoint on the way to being human. Modern chimps have been evolving for the exact same 6–8 million years since our lineages split from a shared common ancestor.  …[Read more]

This theory suggests that during human evolution, we may have lost some ancestral short-term or working memory skills to make room in the brain for other, more complex functions, such as advanced language abilities, symbolic representation, and hierarchical thinking.

Two students ultimately outperformed the chimp on the brief-display condition. The authors conclude there’s no evidence for a fundamentally superior spatial memory system in chimps; intensive training plus strategy can explain Ayumu-level performance.

@jakelafort – yes, Jane Goodall totally opened up the field of primatology, changing a great ape from a “what” to a “who”.

Only a small difference in DNA, but what a difference a DNA makes.

Apparently, it’s all because of our “harsh and risky foraging niche”.  The great apes live in forests where food is easy to come by.  Humans were forced to share and cooperate as soon as their forests died back and they were forced onto the savannah.  Gr…[Read more]

Oh and i should adduce cuz what the deuce that Goodall herself was a theist.

Some new science on gene editing…..

Summary from AI;

Most rare diseases aren’t “rare” in aggregate — 400 million people worldwide have one.
But each specific mutation is rare, so big pharma won’t touch them because the economics are hopeless.

Liu’s new approach (PERT) is a mutation-agnostic gene-editing engine for diseases caused by prematur…[Read more]
