Explaining the punctuation of equilibrium

The April, 2010 edition of Discover Magazine profiles biologist Lynne Margulis, famous for her well accepted suggestion that eukaryotic bacteria did not evolve in linear fashion, solely as as a result of natural selection. Rather,

mitochondria and plastids--vital structures within animal and plant cells--evolved from bacteria hundreds of millions of years ago, after bacterial cells started to collect and interactive communities and live symbiotically with one another. The resulting mergers yielded the compound cells known as eukaryotes, which in turn gave rise to all the rest-the protoctists, fungi, plants and animals, including humans.
There was a shocking idea at the time (1967), but, as described in this article by Dick Teresi, the more recent ideas of Margulis are even more controversial. The Discover Magazine article documents her arguments that symbiosis is "the central force behind the evolution of new species." This position runs counter to the holding of modern conventional scientific wisdom, that new species arise through "gradual accumulation of random mutations, which are either favored or weeded out by natural selection." Margulis holds that random mutation and natural selection play a minor role and that the big leaps in the evolutionary record "result from mergers between different kinds of organisms, what she calls symbiogenesis." The Discover article takes the form of an interview, in which the dominant theme is that "natural selection eliminates and maybe maintains, but it doesn't create." Margulis argues that the laws of genetics "show stasis, not change." She was prompted by the fact that there is no record of major fossil change until 542 million years ago, yet all of a sudden we see the Cambrian explosion. Stephen Jay Gould coined this phrase, "punctuated equilibrium," "to describe a discontinuity in the appearance of new species." According to Margulis, her explanation of symbiogenesis explains these discontinuities and should thus be considered the primary mechanism for evolution. Margulis carefully distinguishes her approach from arguments based on "intelligent design." She holds that those who advocate for "intelligent design" have nothing meaningful to offer to the scientific conversation. [More . . . ]

The clean-up in Japan

I love this article. Yes, I stared aghast at the photos five months ago, immediately after the tsunami. And now, I see these photos showing immense progress in the clean-up. I can't imagine how many person-hours have been invested in this supremely admirable effort under the most difficult of circumstances. What a great testament to the character of the people of Japan.

Accidentally disclosed AT&T memo reveals true reason for proposed merger with T-Mobile

See this analysis regarding an AT&T memo that shoots down AT&T publicly stated reasons for the merger it proposes with T-Mobile. Free Press has distributed a mass emailing that summarizes the true reasons for the proposed merger:

AT&T’s plan to take over T-Mobile is about gouging consumers, destroying a competitor and firing an estimated 20,000 American workers.
More here from Free Press, as reported by Planet Unfiltered:
“We now know the truth: AT&T is willing to pay a $39 billion premium for one reason and one reason only — to kill off the competition,” Free Press CEO [Craig Aaron] said in a statement. “It would cost AT&T one-tenth of the merger’s cost to expand its network than to buy up T-Mobile. Yet AT&T is willing to pay a 900-percent markup to take out a lower-priced competitor and make sure it can lock in and gouge consumers in the future. The only thing stopping AT&T from expanding its network is greed. One plus one does not equal three, but subtracting one competitor adds up to billions in profits for AT&T and thousands of Americans out of work.”

God is on MY side now

I’m tired of justifying my actions based on moral and pragmatic grounds; it’s too often too much work trying to explain that I am motivated to make my tiny corner of the world a better place, or that I’m trying to avoid needless suffering. Justifying my actions based on real-world consequences often requires planning, empathy and evidence-gathering, and I’ve decided that this is too much work. What’s the solution? I have quite recently realized that I am a believer in God, which makes me special and unquestionable. My new outlook germinated about a month ago when I noticed Rick Perry having such an easy time justifying anything he desired, based on things God allegedly told him. Why are you running for President? Because God told me to. Why are going to dismantle social security? Because God told me to. What are you going to do about Wall Street Banks? God will tell me after I allow those nice men to wine and dine me. Such freedom! I was jealous of Rick Perry, so I adopted God too. I like this new power. Because I am now one of God’s special people, when you question me, you question God Himself . . . so you’d better not ever have the arrogance to question me or God. You want to fight me buddy? God’s me Buddy. I like being God, Jr. It’s armor to protect me from all forms of intellectual and moral challenges and evidence. Having God as my Pal lessens my cognitive load, making life much easier, and it’s going to allow me to quickly cut through a lot of moralistic red tape. It’s going to let me invoke my program without having to explain myself. [more . . .]
