Even better than using the median instead of the mean

A proscription on all transitional forms would make it far easier to load the Ark—it would have been empty!

P.S. If you’re completely baffled by the title, it refers to Woodmorappe’s infamous statistical error: calculating the feasibility of Noah’s Ark by estimating average animal size using the median instead of the mean.

    Hilarious! Bust-a-gut, good solid wisdom. Right up there with Gary Larson’s takes on the Ark — “So much for the unicorns. From now on, all predators are confined to C deck”, etc.

    Does it really count as an error if you do it on purpose? I have heard of people using the mean when they should be using the median out of simple ignorance or habit. But who accidentally uses a median?

    I’m not a biologist, so forgive if I ask a silly oversimplification. In reality, wouldn’t most species be a transitional form, with possibly many lost species in between, to another animal?

    Yes, they would, except for the lineages that go extinct without leaving any descendants. Hence, Dr. Meyers’ comment about the ark being empty …

    But the median is so useful! I mean, if you can’t fit all of the brontosauruses and blue whales and giant squid on Ye Arke, just collect a thimblefull of bacteria, viruses, and prions, and presto! n * median_volume becomes much smaller, and you can fit them all in with room to spare!

    O, Teredo!
    They’re my favorite clams.
    with teeth.

    (see, for example, http://en.wikipedia.org/wiki/Shipworm )

    Not a good thing to bring on your ark,
    unless you’re trying to bring down the median time required for animal care.
    “Hey! we can just stick these guys on the *outside* of the ship! They’ll take care of *themselves*!”

    What I always wondered is where did they stick all the diseases? I mean., how did Noah and Co survive Ebola, Marsburg, Dengue, Yellow Fever, Cholera, Thyphus, Plague, hyphilis, Gonorrhea, HIV, Polio, Smallpox, …..

    How many hundreds of icky diseases must each human have had?

    And then there are the animal diseases….
