Cloning is a Silly Issue

As with Prohibition and Abortion, the Stem Cells and Cloning issues are handy distractions from real issues of national import, like infrastructure, economy, and war. The War on Drugs is every bit as successful now as was Prohibition in the 1920's. Abortion is a medical procedure that blatantly favors the rights of the host over the cluster of human cells growing within. Although abortion is periodically effectively outlawed, its incidence is never significantly reduced. Oddly, to mention stem cells brings a knee-jerk retort of "Cloning!" from some quarters. Cloning is only a dangerous issue to those who don't actually know what it is. Let's suppose that the technology were developed to create a healthy baby genetically identical to an existing adult. It would be an expensive procedure, and necessarily take as long as a normal gestation. But mutations occur with every cell division, so the original cloned blastocyst would be subtly different than the donor's original blastocyst, however perfect the methodology. The clone would also be raised in a different family, so we are now slightly farther apart then identical twins raised apart. Much more significantly, the gestation would be in a different environment (womb, timing, nutrition) creating many significant physical developmental differences between donor and clone. I laugh when movie clones have all the same freckles, scars and other developmental marks as the donor. A perfect clone would resemble the donor much like a normal sibling raised separately. Why would anyone bother? Even with livestock. The genetic and health dangers of monoculture tree and vegetable farming are bad enough as a cautionary tale. Most people well enough educated to develop cloning know enough about the principles of evolution to know that duplication of a genome (however ideal it may be) in bulk is a Very Bad Idea. But cloning research is a different issue. The research has very high potential for serendipitous results. As with the accidental discoveries of antibiotics and Teflon, one can only find things by looking for something in the same area, but rarely for the thing itself. Some of the possibilities include: * Growing cloned organs in vitro or in a host. Crichton wrote Congo based on the idea of cloned organs raised in host animals. * Learning enough about gestation to create artificial wombs would be of enormous benefit to premies and other medical problems. * Knowing how to start and stop cell and organ development could well lead to regrowing limbs and teeth and other organs directly in the host. Some legislators are moving to block such research, in case it may lead to the possibility of someday making a clone. But why? Soul? Find me two theologians who completely agree on when and where a soul is created and when it enters a body. Now find me as many who agree as scientists who agree that the soul is a product of biological structure and heuristic experience, a quickly growing number.

Handy list of transition fossils: seven missing links for handy reference

I've often wished that I had a short list of impressive transition fossils handy for the next time a creationist claimed to me that there were no such transition fossils. Well, here's the list I've been looking for, published by the National Geographic. The first fossil on National Geographic's list is the especially compelling find, Tiktaalik, the "fishopod."

Can Science Trump Religion?

This is not a question of whether science can or should prove or disprove the existence or non-existence of God or gods. Some of us believe that we are living in an era of rationalism, or enlightenment. Some, like Dawkins, even hope to see rational thinking purge religious clap trappings from society. The question is, can rational thinking ever purge society of silly ideas? I was reading the Dale McGowan post Best Practices 4: Teach engaged coexistence and he obliquely gives the answer. Consider:

  • Coperincus (ca. 1500) decisively proved that Astrology was unfounded.
  • Avagadro (ca. 1800) proved that Homeopathy was bunk.
  • John Philips (ca. 1840) proved that the Earth was at least 90 million years old (before Darwin published, or more accurate isotopic dating techniques were even imagined)
  • Hubble (ca. 1920) proved that not only was our solar system tiny compared to the galaxy, but that our galaxy is infinitesimal compared to the visible universe.
Surely we would no longer find anyone to believe that the stars predict our future, that water has memory, that the Earth is young, or that the Earth is the sole point of all creation. No amount of education of thinking individuals will ever remove the comforting effects of belief in paranormal salvation for the majority of mankind.

Group selection theory attempts a comeback

Over the past few weeks, in commemoration of the 200th anniversary of Darwin's birthday, we've seen many articles published on the topic of evolution. The November 20, 2008 edition of Nature contains a drawing of Darwin on the cover, and the entire issue is titled "Beyond the Origin." Inside this issue is an article by Marek Kohn titled "The Needs of the Many," an article summarizing current thinking on group selection. Kohn carefully sets out some definitions at the beginning of his article. For instance, he recognizes that modern evolutionary theory is based on the idea that selection "sees" individuals and acts on them through the genes they embody. Compare that to "group selection":

The idea that evolution can choose between groups, not just the individuals that make them up--has a higher profile today than at any time since its apparent banishment from mainstream evolutionary theory. And it gets better press, too. This is in part owing to the efforts of David Sloan Wilson of Binghamton University in New York, who argues that the dismissal of group selection was a major historical error that needs to be rectified. And it does not hurt that he has been joined by Edward O. Wilson, the great naturalist and authority on social insects. They and many others have worked to reposition group selection within the broader theme of selection that acts simultaneously at multiple levels.

Buried in the dispute about the extent to which group selection occurs are numerous definitional issues such as the proper way to define "group," "altruism," and "selfishness."

All-too-human art

In a recent article appearing in Nature, "More Than Skin Deep," Martin Kemp asks what we are to think of Andrew Krasnow's work of art entitled "Flag from Flag Poll." The artwork is a 2 meter long American Flag made out of human skin. Consider, also, the online exhibit entitled "Making Visible Embryos," by Tatjana Buklijas and Nick Hopwood. In Nature, Alison Abbott describes the exhibit as "the story of how embryos have been depicted."
