Scientists recreate evolution of complexity using ‘molecular time travel’

Posted on January 8, 2012 by James Kohl.

“Much of what living cells do is carried out by “molecular machines” – physical complexes of specialized proteins working together to carry out some biological function. How the minute steps of evolution produced these constructions has long puzzled scientists, and provided a favorite target for creationists.”

My comment:

Groups of molecules that happen to stick are credited with tinkering, degradation, and good luck during evolution. Does that mean each of our ancestors as far back as single-celled organisms was preserved because they helped our other ancestors to survive? If so, I have a problem with what appears to be a one-way model. For example, how does the accumulation of simple, degenerative changes over long periods of times cause speciation, which incorporates many of the complex molecular machines present in organisms today? I think the accumulation of simple, degenerative changes in different organisms must stop for one species to establish its ecological niche but I don’t see any explanation for stop-and-start degenerative changes. That’s why one-way models of evolved complexity don’t work for me, but especially when the “one way” is via degradation. For contrast, Lynch et al find no evidence for stepwise evolution.

“There is a broad consensus that many of the genetic changes underlying the evolution of morphology occur by the stepwise modification of individual pre-existing cis-regulatory element modules5,6,29. However, it is questionable whether the origin of complex novelties—such as the origin of new cell types, which involves the recruitment of hundreds of genes—can be achieved by these small-scale changes7,29.”

The importance of the evolved mammalian placenta to human behavior cannot be overstated. The chemical communication that occurs in utero between mother and child probably are responsible for the genetically predisposed mother-infant bond, which sets the post-natal stage for the development of differences in adult behavior. I will have more to say about this in a follow-up post.

James Kohl owns Pheromones.com, and he has published books and award-winning research journal articles about human pheromones. With colleagues he was the first to show that a mixture of human pheromones increases the flirtatious behaviors of women, and increases their level of attraction to the man wearing the mixture - during a real-life social circumstance lasting 15 minutes.

What is the vomeronasal organ (VNO)?

The vomeronasal organ (VNO) is a cone-shaped organ in the nasal cavity, which is believed to be one of the body's receptors of pheromones. More, specifically, the VNO, which is part of the accessory olfactory system in the nose, does not respond to normal scents, but may detect odorless, barely perceptible pheromones.

Other schools of thought believe that it is not the VNO but rather cells in our main olfactory system and their affects on hormones secreted by the hypothalamus that are responsible for the affects of pheromones.

What are optimized pheromones?

Optimized pheromones are lab-certified pheromone formulations that have the optimum concentration of biologically active pheromones scientifically proven to produce behavior-altering results -- particularly as sexual attractants. Optimized pheromone formulations do not necessarily contain the maximum level of pheromones available on the market, but rather contain the greatest degree (and combination)of human pheromones that trigger a conditioned biological response in humans that, in turn, dictate their sexual behavior. Optimized pheromones also release neurotransmitters that directly modify the behavior of the opposite sex, such as triggering sexual excitement. For example:

Optimized pheromones for men are scientifically proven to bring about an increase in the luteinizing hormone (LH) in women, thereby causing a woman to have a heightened sexual responsiveness to a man. This LH surge elevates a woman's predisposition towards sexual activity.

Optimized pheromones for women are scientifically proven to bring about a biochemical surge in men, thereby causing a man to have a heightened sexual responsiveness to a woman. This biochemical surge is what makes a man fiercely determined to copulate.
