Evolution, Morphology and Exobiology

Now, before we begin, I would like to say that I am not proposing any other theory, but that i believe there has to be another way. Please, no arguments, but debates, using reason, facts and evidences. I am inclined to believe that life was formed by another way than the theory of evolution. The bottom line issue that i have with the very basis of evolution is that, even if an amino acid were formed under all the right conditions, which the likely-hood of ONE being formed is very small (That you cannot deny, it may be true, no one has ever proven it can be done without premeditated planning, but also, no one has ever dis proven it either), it takes more than one amino a…

We have created a generic platform to simulate complex ecosystems with intelligent predator and prey agents interacting and evolving in a large and dynamic environment. We have chosen to implement an individual-based model, built upon the predator–prey paradigm. The novelty of our model stems from the fact that each agent behavior is modeled by a fuzzy cognitive map (FCM, a computational tool, similar to a neural network, based on a graph that represents interaction between concepts, such as emotions and desires, perception or action), and evolves during the simulation. The FCM of each agent is unique, and is the outcome of the evolution process going on throug…

Hello people. I am new here. I couldn't find a topic like this so please go easy on me if there was indeed a discussion earlier. When I watch nature channels, I wonder how come the herbivores like rhinos and hippos are so muscular. I don't think their size can be all fat. Or is animal fat non jiggly? It is understandable if large cats are muscular as they would be hunting all their lives and will be physically fit but even with them, some younger adults who haven't quite yet started hunting look very muscular! What do you think is the reason? Do these animals unlike us get muscular "naturally"? Anyone having experience watching them up close?

Why do we laugh? What's the evolutionary point of it? Ok... let me answer the most basic part first: it's a part of our communications, and therefore quite useful. Something unexpected happens that is quite harmless (not dangerous) then there's a good chance that we laugh. If that unexpected event links back to something that happened in the past or has otherwise some meaning to the us, it's likely that we'll be roaring with laughter. It's even funnier then. That's a useful communication to explain a rather complicated concept very quickly. But what is the point of just rolling on the floor laughing, almost completely incapacitated by laughter, tears in our…

If amphibians evolved from fish, which presumably lived in oceans, why are there no salt water amphibians? Or am I mistaken? Or did amphibians evolve from freshwater fish because there were no oceans...?

A human finger bone was found in an Siberian cave, well known for its Neanderthal remains, only this finger's DNA is not Neanderthal. This human may have been in Siberia long before Neantherthal. Perhaps we should be looking for the missing link, some place besides Africa? There appears to be agreement we came out of Africa, but our understanding of that migration is changing. http://www.nature.co...ll/464472a.html -------------------------------------------------------------------------------------------------------------

I was a kind of bored and got reading some stuff in this evolution area. I think evolution is misunderstood. (my opinion) As a read threads here, it seems that the concept of evolution is that of a conjecture where all species (including plants) develop along a line from simple living beings into more sophisticated & adapted ones. It is a part of the conjecture, but IMO it is not the whole story. At each moment of the living Earth history, the whole biosphere must have worked as an interlace of relations between species, a net in constant dynamic equilibrium. If a specie is not adapted to its environnement, it is believed (as I read here around) that evolution is…

if sugar is and fat is so bad for us why do people like them? why is it the high calorie stuff that people like. wouldn't evolution have made people dislike sugar and fat by killing all those that like it?

Has anyone ever been able to describe how evolution seems to know of the surroundings of an animal? For example how is it animals whose natural fur color matches that of their surroundings? Or how did the eye come about? How would it know to make an organ that picks up light waves and how to even translate the information?

Typically, species are defined in terms of a population's inability to produce viable offspring with a different population. How, then, do we define the species with regard to asexual creatures? Is it gross genetic difference? Phenotypical difference?

First of all I'm sorry if this doesn't belong in the right place, I really thought it should be placed here. OK so here's my situation: My father's height is 5' 9" My mother's height is 5' 3" I'm 15 years old and I'm 5' 11" 1/2. Please don't say "That's pretty enough, shouldn't complain!". Also I want to mention I'm currently 231 pounds. (I know I'm fat) But I was 251 pounds 3 months ago so I lost 20 pounds and I'm still losing weight. I want to know what's the height I will reach? I'm starting to grow beard, I have pubic hair, I mean I think my puberty started long time ago, like when I was 12 or 13, and I'm not sure but it e…

I'm having a debate with someone, and something my opponent stated struck me as flat wrong, but I'm unsure how to respond. His statement was: 'For all mammalian species, females have less testosterone than males.' Hyenas are an obvious exception to this universalising statement which I will bring up in due course, but I can't think of any other species. Are there any other species of mammal in which the females exhibit higher levels of testosterone than males? I need more than just a single 'exception' to his claim. Thanks! --Derelitto

I have a very basic understanding of evolution, and find it fascinating but still have gaps/questions. When for example a certain species population is split geographically, and given enough time they slowly begin to differ, due to demands of environment etc there must come a point when they are no longer able to breed with the other group they were split from. But something tells me that the 'cut off line' could not be that neat, as everything else in this process is so gradual and I could not imagine one animal being able to breed with the other group, but who's offspring couldnt I would be grateful for anyone wiser on the subject to shed some light!

Are the large numbers of microorganisms found in the mouth cause for concern? Can someone explain this please. Does not it lead to tooth decay

Is modern evolution theory, by promoting survival, promoting supernaturalism? I am a hard-nosed scientist and analytic philosopher. I have noticed that evolution theory denies yet promotes supernaturalism. It is this two-facedness that I object to. 1) I am told that "copying" is the key to survival. Surely, this is nonsense. If I make a copy of myself do I survive if I, the original, dies? Of course not. Neither do my genes survive. New ones might have been made along the way but that is not "survival" of anything. But, I hear the objection, it isn't the physical form that survives death, it is the pattern of the physical form that survives. Well, no. No - u…

I ran across this from a guy on facebook and he gave me permission to use it freely. I thought you guys might like it. _________________________________________________________________________________________________ I propose a simple poker game where all the players receive 5 cards from a randomly shufffled deck. Then each player shows his cards and the highest ranking had wins. After 1000 games, who ends up with the most wins? The answer is on the average noone, because the cards were random. Now lets play another 1000 games, but after each card is dealt, lets let one player discard up to five cards each of which are replaced by cards from the top of the ra…

What is the scientific explanation for this?

WHY EVOLUTION CAN'T BE TRUE Naturalism-Much of science is subject to naturalism. This is the belief that the only thing that exists is the physical universe and the laws that determine its behavior as exhibited by nature. Therefore Naturalism rejects anything supernatural including God, or, if God exists, then He doesn’t intervene in the physical world. Today much of society is infused with the view of naturalism. This assumption is taught through education, and presented as “truth”. Thus this view then branches out to influential areas which then determine the course of society. The aim goes something like this: We need to get people to think in a certain…

If theory of evolution is true, the organs from apes can be transplanted to humans. If theory of evolution is really true, there are no animals today in the first place. Is there an evidence in science that connect the animals to humans? I mean, where is the link between animals and humans?

Hi People, OK, evolution occurs with a natural random mutation on the DNA strand. If that new specie/variation occurs timely with a change in the environmant which favors that change, that specie has an advantage. BUT, that new organism needs a mate, male/female with that same freak chance of mutation to have occured. Yes, this takes a few hundred thousand years....math takes time. Its all math, you know. Still, you have biologists explaining how if a specie does not have a critical gene pool, it dies off. For example, there have been dwindling populations of say, an endangered specie. There are 24 left (whooping crane in the late 70's). Then that species gene poo…

I often see the term "artificial" applied to human activity and technology both in conversation and in formal academic literature. Granted, we have a greater facility with tools and symbolic reasoning than most creatures, but we evolved in the same fashion. For example, "artificial selection" is often used to describe the domestication and selective breeding of animals. I would argue that this is "natural" selection just as the symbiosis between algae and fungi in a lichen arose from natural selection. You might say we "chose" to selectively breed animals therefore it is artificial. I would say that perhaps the algae or fungi chose too, albeit in a much simpler, seemingly…

Could single celled organisms produce enough oxygen without multi-cellular organisms existing for our atmosphere? The planet's only residents were single celled organisms for over half the earth's history. The majority of successful single celled organisms is determined by population status and its vital role in supporting other organisms ability to survive. I do not see how we could emerge especially with so many complicated processes that require so much energy to produce and maintain during a lifespan. isn't the law of physics state that energy works to reduce itself? It seems to me that single celled organisms could do just fine without larger life forms.
