    Until the environment changes quickly and drastically, at which point the "progressive" organism is SOL

    Re: “Corrections

    Not sure about the "astrological identification" (which would mostly be concerned with zodiacal constellations), but the astronomical enhanced pinpoint of light up above and to the right of the Big Dipper is indeed Polaris. (Despite Ms. Wilburn's conjecture that "what is seen in the photo is a planet" you won't find any planets anywhere near Polaris!)

    Re: “Evolution Isn't Progress!

    Hey Peter, I think Alan John Clark addressed your confusion (a common one). Again, evolution is totally opportunistic. Intricacy, simplicity...nothing to do with it. All that matters is better adaption to environment leading to more successful gene transmission.

    Re: “'Highly Ordered'

    Charles Davy writes, "...the universe is not tending toward chaos at all, but rather is highly ordered and organized."
    The Second Law of Thermodynamics (about as much of an actual "law" as we'll ever get) says otherwise; the cosmos is moving inexorably from a highly-ordered (low entropy) state to one of high entropy, what has been called "heat death" of the universe. Fortunately for us, we're able to temporarily maintain our local order thanks to that big ball of low entropy in the sky responsible for photosynthesis. When the sun goes out, any local order goes with it.
    My two-part column on entropy (9/20/18 and 9/27/18) explains this is more detail.

    Re: “Is Science Done For?

    I received a note saying I should have included, for the discovery of radioactivity, Henri Becquerel and Marie & Pierre Curie.

    Re: “Is Science Done For?

    Dark matter was originally postulated by Fritz Zwicky in 1933, so its not really new. If it led to MOND, non-Newtonian gravity, that would have to be added to my list. (Or if it turned out to be a particle that upset the Standard Model, i.e. WIMP.) But more likely it will explained by regular (but essentially invisible) matter = MACHOs. At this point, nothing to suggest a revolution.

    IOW, dark matter, meh. Dark energy, wow!

    As far as the frequency of revolutionary new discoveries: count the number in the 60 years before and after 1959.
