    As far as I know only 1 species on Earth has the ability to make fire. Then, using tools to kill prey. All other animals
    use only their teeth. When you have that, you go on to written language and numbers.

    Tools are used by our chimpy chums too.

    linkius wikius
    Research in 2007 shows that chimpanzees in the Fongoli savanna sharpen sticks to use as spears when hunting, considered the first evidence of systematic use of weapons in a species other than humans. It has also been observed in the 1970s that some chimpanzees/bonobos use sticks as probes to collect ants and termites.
    There is a lot of other use of tools for various purposes, but I'm not sure how many animals use tools specifically for killing prey. Birds use them for nest-building.

    As above, so below

    Hi Nereid I really don't know anything about the papers, I was just pointing to them as an example of the graph. The graph is seems to be used in a lot of work ( evolutionary psychology ) though mostly to do with only one branch of life, these were just a couple of examples. The graph has a name but I can't remember it, sorry I know that's bad, but it's not my subject.

    So do you not think the EQ of earth species has increase/evolved with time? Leading to new species with greater EQs?
    I always thought adapatabillity would offer a major advantage in evolution, and increased intelligence would allow an organism an advantage. I'm sure you know all the arguments.

    Thanks.

    I'll see if I can find some more up to date material; I expect that more recent papers would not be so, um, sweeping in their conclusions.

    So do you not think the EQ of earth species has increase/evolved with time?
    I think you mean something like 'the species of certain clades (or monophyletic groups) tend to show an increase in EQ, over time'.

    Leading to new species with greater EQs?
    Assuming my restatement, then there certainly seems to be some strong evidence for this, for a small number of clades.

    I always thought adapatabillity would offer a major advantage in evolution, and increased intelligence would allow an organism an advantage. I'm sure you know all the arguments.
    And that does seem to be the case ... but only for a modest number of monophyletic groups!

    Of course, as you pointed out earlier, there is a major exception to this: mass extinctions. The species which seem to have survived such seem to be the boring, small, generalist species in various groups, not the big, glamorous, high EQ ones. This is particularly the case for the PT mass extinction. So, on a planet where mass extinctions were much more common than on Earth, it may be the a high relative EQ would be selected against; it would be a mal-adaptation.

    It would be interesting to know if the intense selection pressure Homo sapiens is putting on large ocean fish species is producing extinction rates which are far greater for high (relative) EQ fishes.

    Jens,

    thanks Jens, I don't usually expect a response to my comments, often only wish to just add my two cents. Cool word "necromancized." Are you an English or language major over there in Japan?
