Evidence for Evolution

Posted on 29. Jun, 2013 by in Science

217In a recent gallop poll, 46% of Americans reject evolution entirely in favor of creationism, 32% believe in evolution guided by god, and only 16% believe in evolution  without any assistance whatsoever. These numbers are much worse than almost every other modern democracy on the planet, with only Turkey being more evophobic than we are.

So as a public service, here is a short list of ten of the most compelling points of evidence for evolution that I could think of. There is a mountain of other evidence, but these ten should be sufficient to keep a creationist busy for a lifetime, trying to explain them away. And if you are a creationist, just ask yourself why none of these objective observations make any sense at all if all life was created together. And then consider just how perfectly they are explained if indeed evolution is true. There really is no way for a reasonable person to deny evolution any longer. To deny it now can only be seen as an act of willful ignorance similar to denying a spherical Earth. You are not going to win this one. Grow up and let’s move on.

1. Fossil record: In all cases fossils are found in strata consistent with their placement in a phylogenetic tree. Simple organisms predominate in older rock, and complexity grows as rocks get newer.  For instance we find the great apes only in the very newest rocks. Makes perfect sense if evolution is true, makes no sense in terms of Creationism/ID.

2. Pseudo genes: These are genes that are still present in many animals, for characteristics they no longer exhibit, but which were present in their ancestors. The genes for teeth in birds is one example. In fact in some cases just by applying a certain protein in the area of the developing beak, a bird will grow teeth. Again makes perfect sense if evolution is true, makes no sense in terms of Creationism/ID.

3. Vestigial behaviors, organs and limbs: Some snakes still have pelvis bones floating in tissue from the time they had legs. Similarly many Whales still have non functional leg bones. Birds with wings that no longer function. Blind fish with eyes that no longer function, or are closed over, because they live in caves. In humans do you ever wonder what goose bumps are for? In apes they raise the hairs on the body for insulation or to look larger when scared. Humans still get them but they no longer serve a purpose since we have lost the hair. The list simply goes on and on. Again makes perfect sense if evolution is true, makes no sense in terms of Creationism/ID.

4. Atavisms: These are like vestigial limbs, but rather than appearing in all animals of a species they are rare occurrences that manifest the entire lost limb or organ in a certain animal. For instance whales have been found with fully developed legs just as they would have appeared in it’s ancestors. This happens when pseudo genes still present in a species are reenabled by means of a mutation. Again, makes perfect sense if evolution is true, makes no sense in terms of Creationism/ID.

5. Geographic distribution: Certain animals are found on islands that are found no where else. But in all cases these animals are found to be closely related to animals living on nearby mainland. In addition, only animals that could conceivably get to the island via drifting at sea or sailing on the wind are ever found there. No large mammals for instance. In addition different closely related species are always found in close proximity to each other. Again makes perfect sense if evolution is true, makes no sense in terms of  Creationism/ID.

6. Fetal development: The general progression of fetal development through evolutionary stages from fish to reptile to mammalian, all the way to tails and hair like our closest relative, that are lost just before birth. Evolution can’t build a new organism from scratch, it must build on what was there before, and fetal development is a record of all the body plans that evolution had to go through over hundreds of millions of years before it ever got to modern humans. Again makes perfect sense if evolution is true, makes no sense in terms of Creationism/ID.

7. Endogenous retroviruses  :  Retroviruses  have the ability to insert their own DNA right into a host cell’s DNA sequence. The resulting, new DNA, is called an endogenous retrovirus or ERV. If this occurs in reproductive cells, the ERV will be passed down from generation to generation, and since the insertion point is random,  if two individuals share even one identical ERV, even if they are of different species, it is extremely strong evidence that they had a common ancestor. Humans share at least 7 of these ERVs with chimps. Game over. This makes zero sense in terms of Creationism/ID.

8. The missing Chromosome: Humans have 23 pairs of Chromosomes, but all other great apes have 24 pairs, Where did the extra Chromosome go if we were descended from a common ancestor? Well as predicted, even before we could sequence DNA, it turns out one of our Chromosomes is an almost perfect copy of two chimp chromosomes, merged into one. Well beyond any reasonable doubt, we share a common ancestor  with chimps. Makes zero sense in terms of Creationism/ID.

9. 99.9% extinction rate: It is estimated that over 99.9% of all species that have ever existed on Earth are now extinct. We know this because most of the fossils we dig up are of species that no longer exist. This is what we would expect to see if evolution were true, since most species will change over time into other species. How does this make any sense at all in terms of a perfect creation, unless this perfect creation was evolution itself? But that’s another article.

10. Mitochondrial DNA: Mitochondria are organelles contained within our cells that generate energy for the rest of the cell. These organelles look very much like bacteria, and in fact contain their very own DNA, separate and unique from the DNA in the nucleus of our cells. Strong evidence that at some point  two bacteria entered into a symbiotic relationship, which enabled the  evolution of multi-cellular life. Like all the rest of this list, it makes perfect sense if evolution is true, and makes no sense at all if creationism/ID is true.

It remains ironic, that those who deny most vehemently, our connection with other primates, resemble them so closely in their inability to comprehend and accept the mountain of evidence that so definitively confirms that reality. Such is the ability of blind faith to short circuit our reason and make us little more than receptacles for dogma.

    Elmo asked me to share this poem:

    FROM MICROBE TO CONSCIOUSNESS

    Imagine the enormity of the task
    magnitude of the planning
    ultra-genius of the physics
    intelligence beyond mortal reach.

    Equations of omnipotent precision
    blueprint of beauty and elegance
    a universe-in-waiting
    laded in a subatomic grain.

    ******
    The speck quivers — detonates
    the blast rips open the void
    a pyrotechnic cosmic dawn
    the birth of space and time.

    Dust swirls at the edge of a galaxy
    coalesces in neutrino-blackness
    an embryonic world — violent in genesis
    pummeled by asteroids
    shock waves sweep the surface
    fireballs rage back into space
    molten plasma tsunamis the globe
    craters hiss geysers of steam
    volcanoes vomit fountains of magma
    liquid iron sinks to the planet’s core.

    The blazing orb spins and cools
    slushy rock hardens to a brittle shell
    breaks apart — drifts on a dense mantle
    crusty plates collide — crunch and grind
    gouge chasmic trenches — sculpt jagged mountains
    vapor shrouds the red sky — boils into clouds
    fierce rainstorms wash the land
    carve rivers and streams — hydrate lakes and seas
    gas belches from ocean floor vents
    primordial sludge bubbles — acids incubate

    life rises from the saline heat—

    biology’s first garden
    thrives – branches — ladders
    upward — ever upward…
    from microbe to consciousness.

    Really nice poem Lou. I might have started it off a bit differently ;), but it’s your poem and I have no problem with a deistic view of the universe. The similarities with atheism far outweighs the differences in my opinion. So thanks for adding a bit of art to the site, and tell Elmo I hope he had a great Thanksgiving. And you as well.

    Cheers,
    Mark

    Think of the opening as metaphorical, kind of a tongue-in-cheek description of omnipotence as a process, a coming together of the initiating physics of the universe, prior to ignition. Deistic in intent? No, but I like to let people interpret as they wish.

    Well in my view, art is at its best when there are multiple interpretations to be had, so it’s just proof you have done it right. That being said, it’s also always nice to hear the author’s intent as well, so thanks for that.

    Hello, i’m from Argentina. I have just read it, and honestly liked it even being Catholic. I’d like to add that you want to make creationist belive evolutionism, when for example, catholisism has accepted it.

    I liked how simple was it written because i know nearly nothing about biology or evolutionism in Spanish, so Engish.

    Greetings =).
