what is the difrence betwen coevolution and convergent evolution?
154427
Coevolution is the joint development of two or more interdependent species, for example, parasites and the animals they live on, such that they adapt to external changes together while,\n\nConvergent Evolution is the tendency of different species to develop similar characteristics in response to a set of environmental conditions.

Evolution is the gradual change in a group of organisms based on surroundings and circumstances that make one population more favorable. Since we do not know what future events might select for homo sapiens, we cannot predict how they will evolve. For example, if we had a full out nuclear war, perhaps a small group of humans would survive that were very tolerant to radiation. There is no way to know. That being said, humans have somewhat overcome evolution because of our advanced medicine- we can let people live who would otherwise be selected against, like people with debilating diseases.

Evolution is the best explanation we have for how species develop. It is supported by a mountain of evidence and is logical to support until new information modifies or discredits it. Unlike God Theory, which is inviolate, set in stone and supported by nothing more than superstition and delusion, Evolution is fluid and developing.

good to hear that you are interesting about evolution. we are studying evolution in our class right now. here's book.\nBiology\nISBN: 080537146X   Author: Campbell    Publisher: Pearson \nEdition: 7    Cover: C \nDepartment: Biology \n\nthis is university level text book. it explains everything you need to know. if you are to buy brand new book, this book will include a CD that has videos too. it costs $122.60 CD. i would try to find it in public library or ebay first.\n\nalso try to serach "evolution" in Google or Google Scholar.\n\nhope it helps!\n\nGood Luck.

Because it's supported by a preponderance of evidence, and is generally accepted within the scientific community, not to mention the minor detail that it's true.\n\nEvolution is a scientific theory that explains the origin of the diversity of species (note that it does not, and is not intended to explain the origin of life). The basic idea of evolution is that mutations result in genetic diversity in a population, and consequently different traits, and different selective pressures favor certain traits over others. In a diverse population, some individuals are better suited to the environment than others, and the individuals that are better suited are more likely to survive to reproduce and thus pass their genes on to the next generation. Consequently, the next generation will have more of the "good" genes and fewer of the "bad" genes than the generation before it. Because the environment is constantly changing, the definition of "good" and "bad" genes is also constantly changing. Something that used to be an advantage can become a disadvantage, and vice versa. More often, however, neutral traits will become either good or bad. Changes in environment can include not only changes in weather or resources, but also competition from other species.\n\nAs the environmental pressures change, the population of organisms changes with it. Over time, the little changes start to add up, and eventually the population will be so different from the ancestral state that it will be considered a different species. The diversity of species results from splitting of populations. If a population is separated by some geographical or reproductive barrier, the two subpopulations will likely evolve in different ways, to become two separate species. Eventually the two species may be reunited, but they will no longer be able to interbreed. Instead, they will compete with each other, and likely diverge even more.\n\nThe theory of evolution is supported by considerable scientific evidence, and is accepted by the vast majority of the scientific community. It is the ONLY scientific theory currently in existence that explains the diversity of species. Some people claim that "intelligent design" is an alternative theory for the origin of species. However, intelligent design is not a theory in the scientific sense. It is not supported by scientific evidence and can never be tested experimentally (not because we don't have the tools yet, but because it is theoretically impossible). Intelligent design provides an alternative to science, not an alternative scientific theory.\n\nScience is not about finding a single piece of evidence to conclusively prove a theory. It's about constructing theories to fit the existing evidence and gathering new evidence that supports or refutes existing theories. Evolution is supported by a preponderance of evidence. While no one point conclusively proves it, when all the evidence is considered in the context of existing scientific knowledge evolution is a well substantiated theory. Intelligent design is not.  What follows are brief explanations of some of the evidence that supports the theory of evolution.\n\n1. Vestigial structures\n\nOne example of a vestigial structure in humans is the appendix. It has no function. Removing it is harmful only in so far as any surgery is associated with certain risks (so I wouldn't have it removed just for fun, but it's because of the surgery not the absence of the appendix). An appendix is found in several mammals. In humans it is small and has no known function. In rabbits and many other herbivores it is large and is used in the digestion of cellulose.\n\nAnother example of a vestigial structure is the hipbones of snakes. Snakes evolved from quadrupeds, and some species still retain not on pelvises, but tiny protrusions of bone in a location that corresponds to the location of the legs in other quadrupeds.\n\n2. Microevo

Its not.\n\nThe word evolved implies evolution, the definition of evolution is any process of formation or growth; development.\nOr more specifically in biology, change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.\n\nHumans did not however evolve from the apes alive today, we simply share a common ancestor.

How did evolution change over time? You mean...how did evolution evolve?  Heh.  The evolution of evolution.  That's funny.

There are different schools of thought on evolution.  Development of one species into a completely different species (macroevolution in a nutshell) is a ridiculous theory, in my opinion.  AND PLEASE REMEMBER THAT THIS IS STILL A THEORY, NOT FACT!  I hate it that people try to pull off this old theory as fact.\nBut I totally believe in gradual adaptations within a species.  That's microevolution (in a nutshell).

MicroEVOLUTION isn't evolution huh?\n\nWhat sort of bizzare nonsense is this? \n\nNext you'll be teling us that microeconomics isn't economics and that microsurgery isn't surgery.

They are similar in that they both study interactions between organisms and their environment (which includes other organisms), and both are concerned with adaptation and change over time.\n\nThey are different in that ecology stresses more the interactions, while evolution stresses the changes over time.  Ecology is concerned with much shorter timespans (months, years, maybe centuries) and how organisms affect and are affected by each other and their environment.  Evolution is concerned with much longer timespans (tens of thousands to millions of years) and how permanent changes appear in organisms as they encounter new or changing environments.

The theory is still the same- altho every thing has been prooven wrong along time ago! There has never been any scientific proof for evolution!  Dr. Kent Hovind is offering a quarter of a million dollars to whoever can proove the evolution theory! Nobody has yet! As it staes the evolution theory is still a THEORY!

Every fossil, every observation in biology points to evolution. There is nothing that goes against it or points to a different way to scientifically explain modern diversity. There is not one fossil or one piece of DNA that does NOT point to evolution.\nCreation relies on a lot of belief and the ability to dismiss all the known evidence, since ancient Greece to the present time, in the case for evolution.\nEvolution, on the other hand, keeps presenting solid evidence, regardless of those who believe otherwise. \n\nHere is a theoretical example of natural selection and adaptation.\n\nSay you have an island, about twenty miles from any other island, where there is a species of bird, say finches. In any population of birds, there is going to be a variety of beak sizes and wing sizes, (like nose and ear size, and height variation in humans), suddenly there was a drought, lasting several years, and the main food source of the finches, say, sesame seed, was destroyed, and all they had to eat was wheat, which is harder to break and eat than sesame. \nWhat characteristics would give one bird an advantage over another? Those with smaller beaks would have more difficulty cracking the wheat and feeding it to any baby birds, therefore they would have less live young. Those with largeer, stronger beaks would crack and eat more wheat and have more live young. Chances are, that their offspring would have, on average, larger, stronger beaks than those of small beaked finches. The stronger your beak, the more you eat, the more children you have. \nSo what other characteristics? Those with stronger, larger wings could try to find other food, but if they can't make to the other island, they die, those that make it to the other island, and if it has food, will have, on average, larger wings than those that didn't make it. They wil have more children, who, on average, will have larger wings.\nThese are simplified examples, it is more complex than this, but the basics are there.\n\nAnother, real life example is the Peppered moth.\nHere is the Wikipedia link\nhttp://en.wikipedia.org/wiki/Peppered_moth_evolution\n\nThis is evolution at work.\nRead more about evolution, but do it with an open mind. It wiil be of no use looking at evidence if you have already decided to reject it. Remember, you are doing science, at that is what scientist do. The more you read, the more you will understand. Try "Origin of Species " by Charles Darwin as a start, or try Google for a summary.\n\nGood luck to you.
