Reduction in the time range of a species

  1. Feb 24, 2015 #1
    6) REDUCTION OF DURATION? Why are the durations of species of

    hominids decreasing over time? The more modern the hominid, the

    shorter its existence. For example, according to wikipedia, Homo

    erectus lived from 1,900,000 BC to 70,000 BC. By comparison, the

    more recent neaderthals lived from 130,000 BC to 40,000 BC. Why is

    the existence of the neanderthal so much shorter?

    My guess is that it's the same reason that piracy is inversely related to global temperatures.

    I would be inclined to suspect that the shorter modern ranges are mainly due to increased information. That decreases the "standard deviation" involved.

    I see, thank you
