Scientists Discover Fish in Act of Evolution in Africa’s Greatest Lake

In what could be a first in the world, a fish species known as cichlids has been observed by scientists in the act of splitting into two distinct species in Lake Victoria, Africa’s largest lake and one of the world’s biggest fresh water bodies.

This may be remarkable because what is causing them to diverge are adaptations to their vision as animals and plants try to cope with increased pollution and the effects of climate change. The change is also happening without geographical isolation, which was thought to be a precursor for evolution.

The researchers showed that the eyes have adapted to this difference so that fish that live in deeper water have a pigment in their eyes that is more sensitive to red light, while shallow-water fish were sensitive to blue.

Evolution stops here ?

clipper's remarks: This is an interesting read, yet biological evolution is only part of the story of human evolution, perhaps a tiny part at that. Moreover, biodiversity in human populations have new sources that are not considered in this article. Many genomes that would have been selected out of the gene pool in older days are now propagated. Made a clip about that a while ago.

For centuries, writers have attempted to predict the future of the human race.

Some have argued that we are destined to evolve into super-beings, others that we are turning into dim-witted goblins incapable of anything more demanding than watching TV.

But according to a leading geneticist, both visions are wrong because human evolution has ground to a halt.

Professor Steve Jones, of University College London, says the forces driving evolution - such as natural selection and genetic mutation - no longer play an important role in our lives.

The people living one million years from now, should Man survive, will resemble modern-day humans.

We now know so much about the process of evolution that we can make some predictions about what might happen in future,' said Professor Jones in a lecture on Monday.

Evolution is driven by natural selection and mutation.

Genetic mutations create traits which, if helpful, give individuals a competitive edge over rivals.

Human evolution coming to a halt

Human evolution is grinding to a halt, according to a leading genetics expert.

Mutation rate was also slowing down, he said. Although chemicals and radioactive pollution could cause genetic changes, one of the most important mutation triggers was advanced age in men. "Perhaps surprisingly, the age of reproduction has gone down - the mean age of male reproduction means that most conceive no children after the age of 35," said Prof Jones. "Fewer older fathers means that if anything, mutation is going down."

Random alterations to the human genetic blueprint were also less likely in a world that had become an ethnic melting pot, according to Prof Jones.

"Small populations which are isolated can change - evolve - at random as genes are accidentally lost. Worldwide, all populations are becoming connected and the opportunity for random change is dwindling. History is made in bed, but nowadays the beds are getting closer together

We are mixing into a global mass, and the future is brown."

A fitting reminder (and some good advice) from Daniel Chun:

"Consider all the meaningless shit that we become obsessed about — ex-girlfriends, neighbors' dogs, celebrities' vaginas — and now think about this: a 72-year old liar with anger problems might become the most powerful person in the world. And if he dies, he'd be replaced by a babbling, evolution-doubting, Supreme-Court-case-not-knowing woman whose knowledge about the world comes from a 3-week cram session. This deserves one month of your obsession. [...]

"The contrast between Obama and McCain could not be greater. This is like choosing between an orgasm and a punch in the throat. The fact this is a close race is a terrifying outrage, and every single person should be doing everything they can about it... Go knock on some doors. Make some phone calls. Make a donation. Recruit your friends. You only have to do it for a month. This shit makes a difference

Human evolution is grinding to a halt because of a shortage of older fathers in the West, according to a leading genetics expert.

Fathers over the age of 35 are more likely to pass on mutations, according to Professor Steve Jones, of University College London.

Speaking today at a UCL lecture entitled “Human evolution is over” Professor Jones will argue that there were three components to evolution – natural selection, mutation and random change. “Quite unexpectedly, we have dropped the human mutation rate because of a change in reproductive patterns,” Professor Jones told The Times.

“Human social change often changes our genetic future,” he said, citing marriage patterns and contraception as examples. Although chemicals and radioactive pollution could alter genetics, one of the most important mutation triggers is advanced age in men.

This is because cell divisions in males increase with age. “Every time there is a cell division, there is a chance of a mistake, a mutation, an error,”

Citizen Enforcers Take Aim

The public urge for punishment that helped delay the passage of Washington’s economic rescue plan is more than a simple case of Wall Street loathing

The fury is based in instincts that have had a protective and often stabilizing effect on communities throughout human history

recent research suggests that in individuals, the fairness instinct is a highly variable psychological impulse, rising and falling in response to what is happening in the world

hardens in times of crisis and uncertainty

From the point of view of evolution, it’s not a problem but a solution

psychologists demonstrated how easy it was to influence how often, or how intensely, people acted on such urges to punish.

Running thousands of computer variations of the investment game, scientists have found that the strategies that pay off the most are tipped toward cooperation.

most successful strategies is the simplest one: tit for tat

Ovulatory cycle effects on tip earnings by lap dancers: economic evidence for human estrus?

we examined ovulatory cycle effects on tip earnings by professional lap dancers working in gentlemen's clubs. Eighteen dancers recorded their menstrual periods, work shifts, and tip earnings for 60 days on a study web site. A mixed-model analysis of 296 work shifts (representing about 5300 lap dances) showed an interaction between cycle phase and hormonal contraception use. Normally cycling participants earned about US$335 per 5-h shift during estrus, US$260 per shift during the luteal phase, and US$185 per shift during menstruation. By contrast, participants using contraceptive pills showed no estrous earnings peak. These results constitute the first direct economic evidence for the existence and importance of estrus in contemporary human females, in a real-world work setting. These results have clear implications for human evolution, sexuality, and economics.

Is Aging an Accident of Evolution? Scientists Say "Yes"

"Everyone has assumed we age by rust. But how do you explain animals that don't age? Some tortoises lay eggs at the age of 100, there are whales that live to be 200 and clams that make it past 400 years."

Prevailing theory of aging challenged by Stanford Universit

Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage similar to rust. The Stanford findings suggest specific genetic instructions drive the process. If they are right, science might one day find ways of switching the signals off and halting or even reversing aging.

“Everyone has assumed we age by rust,” Kim said. “But then how do you explain animals that don’t age?”

“A free radical doesn’t care if it’s in a human cell or a worm cell,” Kim said.

If aging is not a cost of unavoidable chemistry but is instead driven by changes in regulatory genes, the aging process may not be inevitable. It is at least theoretically possible to slow down or stop developmental drift.

Art has the magical power to give provoke emotional as well as intellectual thinking

My desire as an artist is to create compelling images of beauty and power that serve to promote our conscious evolution as human beings.

I have discovered that the more intensely personal my vision is, the more universal its appeal

My wish is to tap into the divine source of being, to consciousness, to spirit, and to bring into visual awareness some images of the knowledge revealed

To this end I like explore themes of Awakening Consciousness, Divine Sexuality, Political Realities and Living in Harmony with Nature.

Terence McKenna - Seeking the Stone Part 1

clipper's remarks: The first part of a video of the seminar , in which Terence McKenna present his perspective on the idea of a spiritual path for all and an impending transformation of the human world . In his singularly lucid , prosaic style , McKenna presents profoundly compelling ideas that challenge our beliefs and encourage our participation in the creation of a new social reality. He champions the individual’s freedom of choice in deciding one’s own sexual and spiritual development and techniques. He highlights the role of hallucinogenic plants in shamanic societies and their impact on the evolution of human cultures. See why this cyber-techno-shaman is drawing freethinking crowds wherever he speaks and find out what role you may play in the unfolding of our “post-historical future” as we approach a major “concresence” in human history.

Berkeley notices a creationist

Parents in the Berkeley Unified School District are horrified to discover that one of their elementary school teachers is a creationist.

Parents said that Martin had listed Santa Claus, the Easter Bunny and Harry Potter under fiction on the blackboard, which promptly reduced some of the 8-year-olds to tears, after which she made the comment about God. ["the only thing they should believe in was God"]

They said that Martin then said that she didn't believe in evolution or the Big Bang theory either.

Usually it's us atheists portrayed as the disillusioning bastards who shatter small children's happy consoling beliefs (and it's true: nothing warms the shriveled valves and atrophied muscles of my tiny dark heart than to visit department stores at Christmas time and announce to the waiting lines of tots that Santa is dead).

it's about time the sheltered elite enclaves woke up to the fact that the creationist movement is working its tendrils in everywhere.
