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]

Scientists can and do cling to pet theories.

Admitting error is the ideal but defending one’s career is the reality. The embarrassment cost is tiny, but the career costs can be enormous.

There have been scientists who continue to push false and even harmful theories even after they’ve been completely discredited, s…[Read more]

Personally, I disagree somewhat with the heading that “Groupthink in science isn’t a problem; it’s a myth.”

In principle, yes. In practice, Groupthink happens whenever careers, funding, prestige, or consensus incentives push people to ‘not rock the boat’. Science has mechanisms to counter this, but those mechanisms are imperfect.…[Read more]

From my experience, if you want to convince a scientist of new ideas, they are often willing to listen, as long as you come with a convincing argument.  I find this is very different from politics or religion.

The enemy is where someone doesn’t like to admit they…[Read more]

This is going to be a hugely successful album. Millions of plays already on Spotify. Not my usual scene but the musicianship is top class.

There’s no evidence that a cartel vs government conflict is directly causing measles vaccine supply problems in Mexico. But cartel control of territory does indirectly make healthcare delivery harder in some regions. So the relationship is indirect and structural, not the main driver. Public-health workers sometimes avoid cartel-dominated areas. T…[Read more]

Did I not answer your questions? Oh, I didn’t! I would call them secondary to the main questions about R nought, the anti-vax movement, and flaws or laziness in human cognition.

@PopeBeanie – Yes, you are correct with the basics of ‘R Nought (12-18). But it does not explain why Canada lost elimination status before the US. But elimination statu…[Read more]
