Evolution, Morphology and Exobiology

What accounts for diversity. ( No conceptual variables please) If we say evolution as in adaptation, then the question is why adapt. If the one thing is capable of sustaining it's life, then what reason would it have too become something different yet similar.or diversify.?

There are a lot of different studies floating around that place the non paternity rate of fathers in Europe and Northern American low as 1-3% to high as 28-30 percent. http://www.isogg.org/wiki/Non-paternity_event What impact does this have on the child being raised by a non biological parent believed to be a biological one? Just as various types of stress affect hormones in children which alter development does exposure to a parent with specific shared genes alter the expression of those genes in biological children? For example; do I have my fathers nervous tick as result of emulating him, experiencing his tick trigger something in my genes, or as a matter of geneti…

My feeling is that the autonomic nervous system governed life in early man but the central nervous system "evolved" rapidly, in fact so rapidly, that our course of life came to be determined by the latter more than the former? My query is whether this is a continuing process or is it subject to limitations governed by evolutionary constructs ? Please advise.

In financial jargon bears and bulls are used to signify the down-trend and up-trend of the stock indices. Does this have a basis in reality? Is this tied to the metabolic (anabolic / catabolic) differences that exist among species? Please advise.

I came across something the other day that was curious to me. An angler was demonstrating to someone how a green laser pointer can spook off water birds that are causing a nuisance. He pointed it at a coot's head and sure enough it flew off. He then pointed it at a moorhen that was pretty close in the bushes and it carried on completely oblivious even though the light shone across an eye at times. Does this mean that moorhens are totally blind to green?

I believe the "carapace" protects only the thorax of the grasshopper above the legs. If true is it also true that the abdomen is protected with an exoskeleton? Is this exoskeleton on both dorsal and ventral sides?

Does the Brain initiative also has the ambition to examine biological differences(physiology, gene activity, morphology) of brains between heterosexual women and men. And will they also examine further the neurobiology(gene activity, cell structures, morphology etc.) of homosexual brains and transsexual brains?

1.how large the sample of study darwin conducted was? 2.how many accurate prediction the theory has made? 3.what kind of sampling method darwin used? probability or non probability? 4. did darwin have any researcher bias i.e. his thought was effected by somebody's idea? 5. what is the effect size of the scientific field where darwin conducted research?

Humans (and other mammals) have a four-chambered heart that beats more than 2 billion times during the average lifespan. Could this organ have been more efficient ? And what if we had a 3 chambered heart ? Please advise.

Does the cosmic microwave background interact with a person's biomagnetic field? Does this have a perceptible effect on the human aura and can we perceive it (through measurements)?

Articles on the matter explain how everything started out with a bacteria that evolved into all the complex life forms we know today, during the course of millions of years. But one thing which hasn't been described is how frequently and to what extent a newborn had to experience mutations in order to evolve. I got curious because I noticed that at this day, few large creatures experience any visible mutations... except of course traits like face shape, fur color, etc. Almost as if humans and most animals people encounter stopped evolving... or rather the process got too slow to even notice. I'm curious since this would help better understand how fast life started div…

I found a person using mathematical formulas as a way of bullying through his argument, but as you can see he posts them ambiguisly without defining. Please help? Is he missinterpeting formulas? The iconoclast Yesterday 12:40 PM +George Forsyth sir fossil records violates the mathematical formulation of the evolutionary process. I guess that is too much for you to grasp. i wild suggest you visit your EPSILON DELTA DEFINITION of continuity you learned in your first year in college. you can't talk yourself out of this. there are no intermediate fossils. time is a continuum The iconoclast 3:04 AM +Zgg Why don't you impress me by stating…

Does Maslow's theory of need hierarchy have as it's base evolutionary constructs? Does the peak of the Maslow pyramid represent the attribute of a "evolved" mind? (self - actualization)

I got yet another questions, directed mostly at people knowledgeable about evolution ( CharonY, Arete, chadn737 etc.) How did fair skin color evolve and got fixed in the population? The trait is dominant pretty much only in two regions of the world - Europe and East Asia. One dude whom I know from another (Polish) discussion forum says that the prevelance of fair skin and blonde hair in Europe is due to sexual selection - it is easier to spot various skin imperfections and aging signs on a lighter skin than it is on a darker one + blonde hair are (I don't know what he based his opinion at) thinner and more pleasant to touch. He wrote an entire lenghly essay (…

The reasoning of racists seems simple enough. If we developed a unique skin tone, perhaps we developed other unique genetics that influence things like intelligence or civility. Nonetheless the concept of race was shown false by genetic analysis, which raises the question of why skin color changed, but nothing else changed. Please criticize my response to this question, or provide your own response. EDIT: Actually, nearly everybody has some melanin in their skin, so the gene is still expressed to some degree. Read post #9. My understanding is that darker skin is due to pigments deposited in the skin. Lighter people have less of these pigments, which means th…

Does evolution require selective breeding to move forward? I've read articles about stress changing DNA and how in an individual lifetime DNA can be impacted by environment. So what I'm asking is, is it possible to adapt without selective breeding?

This made me laugh and got me thinking; we undoubtedly have a measurable impact (not just from scientific/agricultural study) on the evolution of much fauna and flora of this planet. My question: how much and how might it colour our future, for better or worse?

Could Price's equation be used for the development of artificial intelligence? http://en.wikipedia.org/wiki/Price_equation If the development of AI were approached differently, where instead of having one particular intelligence and having multiple "neurons" become the artificial intelligence, could Price's equation be used to make these groups of intelligence become one artificial intelligence, since the idea would be that some "neurons" would die off while others would survive. I hope this isn't confusing for people to read. If it is, I can clarify.

I recently heard someone say that they thought humans were obviously the most superior species. I found it difficult to argue against, but it didn't seem right to see it that way. I guess it's not a very scientific question because it's open to opinion. It also seemed a slightly arrogant way to view us, and one which could lead to abusing our position in the natural world. Any thoughts?

I know that genetic mutations are a major part in allowing the next generation to continue on because in order for there to be the "choice" of an offspring that can be fit for a certain environment there must be multiple "choices" available for that species to live on. However, I assume there must be a particular amount of offspring to allow the needed gene to move onto the next generation. I also assume that there is a required amount of that particular species(parents) to allow the probabilities to allow that particular offspring to be born and carry on with the gene. If all my assumptions are correct, and correct them if they are wrong, is there an equation to dete…

Well maybe evolution is what you think. However, most of the people I have come across who talk about evolution speak of the idea the what they consider to be the driving force behind evolution. Although they have different names for the force, ultimately it comes down to genetic mutuation. If you have been thinking that mutation is the cause behind all but a small fraction of evolution than the name for this post I have created is accurate for whoever is reading the words I am now writing. Evolution is not what you think if you think genetic mutation is the reason for the existence of the massive evolutinary phenomenon. The only time genetic mutation had a huge impa…

Hi. Amateur gardener learning, been told/read that higher temperatures (to a limit, and unrelated to sunlight amount) are more convenient for plant growth -at least for garden vegetables- But roots should be kept cooler ? Irrigation in form of artificial rain, as sprinklers/misters can promote undesired fungus, better water only the soil sorrounding* the plant. Irrigation in form of artificial rain, as sprinklers/misters will reduce the plants temperature they prefer for optimal growth, specially when the water source is colder than ambient. * Surrounding somewhat far from stems to promote roots expansion seeking moisture. Do you share the opinion then, th…

It is known plants need their roots to absorb oxygen for proper development. -I think- Seems to me the amount of oxygen available deep in packed soils should be minimal or near to nothing, but, there is still some availability. I would like to know if such oxygen is necessary for the root itself or for the general development of the rest of the plant. If the oxygen is to develop roots, something does not click in the evolution, where plants could had developed some above ground tissues for capturing it or exposing some of their roots to air. If the little oxygen available in the soil is to develop general above-the-soil tissue growth, well, same situation; with s…

I'm sure this has come up many, many times on here. So I apologize if I'm upsetting anyone by starting this thread. If this needs to be moved, I understand. Essentially, my brother-in-law believes there's no evidence for evolution or at the very least, there's no evidence for evolution which can't be "interpreted" as evidence for creation as well. I don't typically engage in these sorts of debates with people, believe what you wanna believe, ya know? But he presented it as "I believe what I do because the evidence supports it and if you can show me otherwise, I'll change my views". So, naturally, I attempted to explain evolution and the evidence to him. It's been nearly…
