  ESR | February 9, 2004 | Courage, not denial: An interview with Dr. David Buss
However, a couple of years ago at a gathering, I heard a young lady with a background in psychology proudly relay to those around her that she had studied "under Buss." I was the only one present who knew the individual to whom she referred and also the importance of her claim.
DDB: Evolutionary psychology represents a theoretical synthesis of the principles of modern evolutionary theory with principles of modern psychology.
Evolutionary psychology brings a formidable set of theoretical tools to understanding psychological mechanisms that have been largely absent from the field of psychology for the past century--inclusive fitness theory, sexual selection theory, game theory, and many more.

 Evolutionary ecology - Wikipedia, the free encyclopedia
Evolutionary ecology lies at the intersection of ecology and evolutionary biology.
The main subfields of evolutionary ecology are life history evolution, sociobiology (the evolution of behavior), the evolution of interspecific relations (cooperation, predator-prey interactions, parasitism, mutualism) and the evolution of biodiversity and of communities.

 Genetic Algorithms and Evolutionary Computation
The evolutionary postulate of common descent has aided the development of new medical drugs and techniques by giving researchers a good idea of which organisms they should experiment on to obtain results that are most likely to be relevant to humans.
Evolutionary algorithms, on the other hand, have proven to be effective at escaping local optima and discovering the global optimum in even a very rugged and complex fitness landscape.
The evolutionary data-mining algorithm was tested on a real-world database of 100,000 subscribers provided by a Malaysian carrier, and its performance was compared against two alternative methods: a multilayer neural network and a widely used decision-tree-based algorithm, C4.5.

 Evolutionary relay - Wikipedia, the free encyclopedia
In evolutionary biology, evolutionary relay describes how independent species acquire similar characteristics as a result of their evolution in similar ecosystems, but not at the same time.
Some species of pterosaur actually had hair or fur, presumably as a result of separate evolution, as the common ancestor of the archosaurs (whence pterosaurs are thought to have come) was quite distant from the therapsid mammal ancestors.
Evolutionary relay is a similar phenomenon to convergent evolution and parallel evolution, but they can all be distinguished.

 [No title]
However, the first approach is weaker because it ignores differences between the relay of media and control, requires the disruption of encoding formats, and introduces significant overhead at each node.
The distribution path is used for the relay of content m from P to S; for example, Figure 8(a) shows the distribution path p[P[sub]1[/sub], S[sub]2[/sub], m].
Therefore, means to secure the relay of content across the interior of the overlay (such as an encrypted media tunnel between sources and receivers) are desirable.

 The Role of Dreams in the Evolution of the Human Mind by Michael Franklin and Michael Zyphur
The leading theory addressing the adaptive qualities of dreaming uses the concept of virtual threat, defined as a dream-state wherein a threatening situation is constructed virtually, and explains that through the rehearsal of various threatening scenarios we may be better equipped to handle real-world threats (Revonsuo, 2000).
While this theory offers a plausible evolutionary account of dreaming, the goal of the current paper is to extend the theoretical underpinnings of this hypothesis by commenting on other fitness-enhancing aspects of dreams and the broader influence of dreaming in the evolution of higher mental functioning.
Despite this subjective nature of dreams, an evolutionary analysis of dreams should not be disregarded and considered outside the realm of scientific inquiry (although for a competing view see Thompson, 2000).

 Pinball Feature Story
Not to criticize the Gottlieb engineers - after all this was very early in the electro-mechanical (EM) game evolutionary period, and they can be forgiven for not worrying about the home repair person 59 years into the future - but to point out the some shortcomings compared to their later efforts.
Some switches were shown with relays in the tripped position, counter to later conventions to show the game state with the game reset and ready for ball 1.
The circuit actually has each of the 7 trip coils in series with the B relay, which is a control relay that should trigger the C relay to score 1000 points.

 The Magic of Relay Mirrors
Relay mirrors may be the key to cost-effective laser weapons systems.
A benefit derived from separating the RM platform and the beam generation source is that enhanced target tracking and aim-point maintenance from the relay to the target occur through a more benign environment than for direct attack.
Atmospheric compensation and target tracking tasks are easier due to the cooperative path to relay and the less dense air from the relay to the target.

 Courage, Not Denial: An Interview with Dr. David Buss - Bernard Chapin - MensNewsDaily.com™
BC: Why does evolutionary psychology evoke such strong reactions in people?  I’ve noted that when I discuss basic principles with those who have never heard of it before I am met with either enthusiasm or anger.  There seems to be little in between.  Why might this be so?  You are the perfect person to ask.
Most universities now have at least one evolutionary psychologist, and it's growing all the time.  It's still opposed at some universities, but the general trend is positive.  There is no going back.

Compassionate reciprocity and evolutionary panaltruism giving rise to life-centered cosmologies, concurrent with mounting validation of the strong version of panspermia, usher in the age of cosmic genealogy on Earth.
Demonstrating human predisposition to compassionate reciprocity and evolutionary panaltruism, a democratically planned global economy implemented through the United Nations (with built-in mechanisms for optimum input and oversight guaranteed to all member states) mirrors in a very real sense an effort already underway through the vision of
Other than that which may be surmised through extrapolation, knowledge of the Universe beyond the boundaries of the observable universe of any communicating planet ("observable universe" as circumscribed by state-of-the-technology of evolving intelligent life) is directly proportional to the degree to which an exchange-relay of knowledge exists between communicating planets with overlapping "observable universes."

 Cancer researchers found a new mechanism potentially explaining evolution of signalling pathways
A relatively small number of evolutionary conserved genes are responsible for controlling the development of the diverse range of animal species.
The signal transduction molecules and mechanisms of major developmental signalling pathways are thought to be evolutionary conserved between invertebrates and vertebrates in such a way that if a signalling pathway is present in a given organism, it includes all the major classes of components found in humans.
Because of the lack of intermediate forms, the evolution of these complex signalling pathways is not understood in detail, and the emergence of signalling pathways with multiple specific and essential components has even been used as an argument against evolution.

 The Sociobiology of Information Architecture - Boxes and Arrows: The design behind the design
Born blind, deaf, and mute, shuffling around in the darkness at 30 miles per hour, grasping for food, searching for mates, the life of your average bacteria (or any of the several trillion single-cell organisms on the planet) is invariably nasty, brutish, and short.
In one of those rare bursts of evolutionary activity (what Stephen Jay Gould famously called “punctuated equilibrium”), a sudden wave of life forms is taking shape during the so-called Cambrian Explosion.
Thanks to the conceptual foundation of sociobiology and, more recently, evolutionary psychology, we are beginning to understand the complexity and sophistication of nature’s super-organisms, some of them seeming to exhibit properties once thought the exclusive province of humanity: language, reason, even the outlines of culture.

Thus, a packet entering the network could have one routing path determination made, have a label put on it representing that fixed path, and then be quickly and efficiently label-switched through the network.
If this sounds to you a bit like frame relay with label switching according to virtual circuit identifiers, but with IP protocols used for routing, you are not far off.
In fact, over half the traffic carried by frame relay networks is IP, in large part due to the need for QOS guarantees.So, while losing its original purpose, MPLS gained a more important one: traffic engineering for QOS assurance.

 Newswise
Researchers from the Northeastern Ohio Universities College of Medicine have revealed the genetic basis behind one of the best-documented examples of evolutionary change in the fossil record: how whales lost their hind limbs.
In dolphins, however, at least one of the genes drops out early in the race, disrupting the genes that were about to follow it.
That causes the entire relay to collapse, ultimately leading to the regression of the animals' hind limbs.

 SMB - May 2001 Newsletter
Many scientists working in Mathematical/Theoretical Biology, Ecology, or Evolutionary Biology, will be familiar with the work of the Theoretical Biology group at Leiden University, led by Hans Metz since 1985.
A number of fundamental contributions in the field of modeling animal behavior, structured populations and, of late, adaptive dynamics and evolutionary theory have been the products of this group during the last 20-25 years.
However, we all would appreciate it if you were to weave in a few sentences stressing the need for safeguarding evolutionary biology, or population and organismal biology, against the onslaught wrought by an overly vigorous competition from the molecular sciences.

 Intelligent Design the Future: Facts and Factoids
Complexity may abound, and evolutionary histories may be obscure and even inexplicable but, warned Le Conte, we must never doubt that such histories are true.
Half a world away Le Conte's metaphysical certainty was matched by Teilhard de Chardin who proclaimed evolutionary thinking to be a postulate to which "all systems must henceforward bow and which they must satisfy in order to be thinkable and true." These were philosophical rather than scientific findings.
The dual mandates that (i) science must adhere to methodological naturalism and (ii) evolution is a fact, serve to diminish the importance of the empirical data.

 Multi Protocol Label Switching Forum
The bank needed equipment that would permit existing applications to take advantage of the speed and reliability of frame relay and at the same time allow the evolutionary growth on new applications.
The first challenge was that the major protocols the banks used (Unisys Burroughs and IBM SDLC) were not those commonly handled by either frame relay networks or frame relay access suppliers.
The frame relay equipment chosen by Washington Federal can handle a wide variety of polled protocols in addition to the two required.

 History
These were young relay runners who had been trained since childhood for the task of carrying messages from tambo to tambo.
The message would be relayed for hundreds of miles by hundreds of runners, until the last runner reached Cuzco and told the message, exact to the original word, because a severe punishment awaited the transmission of an inaccurate message.
The chasqui relay system was so fast that runners could carry fish from the coast to Cuzco in the high Andes and it would still be fresh when it arrived.
