Are we humans simply remodelled apes? Chimps with a tweak? Is the difference between our genomes so minuscule it justifies the argument that our cognition and behaviour must also differ from chimps by barely a whisker? If “chimps are us” should we grant them human rights? Or is this one of the biggest fallacies in the study of evolution? NOT A CHIMP argues that these similarities have been grossly over-exaggerated - we should keep chimps at arm’s length. Are humans cognitively unique after all?

When Fire Approaches, Chimps Keep Their Cool
Interesting article in SCIENCENOW about the work of primatologist Jill Pruetz with the Fongoli chimps, regarding their behaviour toward fire. Instead of panicking and totally failing to comprehend the nature of fire, she noted that the chimps reacted to brush fires by carefully forging paths to avoid the outbreaks. If you allow that human mastership of fire required three stages: conceptualizing it (meaning also to lose fear of it); starting it; and containing it, Preutz argues, you can see chimp behaviour, perhaps, as a clue as to how some putative hominin ancestors reacted to fire, which eventually led to employing fire to cook food etc. I always have a problem with "chimps give clues to origins of human behaviour" stories because we did not evolve from them. So, if the logic is defensible it is only by virtue of arguing that chimps retained some vestige of loss of fear of fire that was present in the common ancestor of chimps and humans.
