How is co-evolution significant in community ecology?
because it determines whether a species will evolve to keep up with its predator or prey

Calmly explain the definition of a theory i.e. a hypothesis which has been supported by much and varied evidence and has made tested and confirmed predictions.
However, those who make this claim often use it to justify personal opinion, so a logical explanation won't do much to change their mind (if they even listen to it at all).
Do any scientists today who are not creationists express dissent from Darwin and his views?
Such a person would have to meet three requirements:
1) Publishes articles in peer reviewed scientific journals.
2) Religious or not, he/she doesn't concern him/herself with creationism.
3) Objects to evolution.
I know of people who publish scientific articles and aren't religious/creationists - but they don't object to evolution.
I know of people who publish scientific articles and object to evolution (though not simultaneously) - but they are creationists.
I know of people who object to evolution but are not creationists - however they don't publish.
I know of no people who meet all three criteria.
Any proposition can be denied by those who do not wish to accept it, no matter how strong the evidence is. However, evolution can not rationally be denied. Scientists say they regard it as fact.

Do germs have anything to do with evolution?
By "germs" I have to assume you mean bacteria. And yes, it is supposed that the first organism was a prokaryotic cell, followed by eukaryotic cells such as plants.
How does natural selection enable populations to grow?
The growth or shrinkage of populations has nothing to do with natural selection, but with the availability of resources, and the ability of organisms to utilize those resources. This is also known as 'carrying capacity'. The natural tendency is for organisms to produce more offspring than the environment can support. So if the environment supports more individuals, then the population will automatically grow. If conditions change and the environment supports less individuals, then some individuals will starve or be otherwise unable to reproduce. Natural selection, in this case, "determines" which individuals pass, and which do not.
How does Mendel's theory of inheritance support Darwin's theory of natural selection?
Mendel's laws deal with the transmission of genes between individuals. Evolution deals with changes in gene frequencies within and between populations.Population genetics, which mathematically analyzes how gene frequencies change over time in populations, is the backbone of evolutionary genetics, and it is based on Mendelian genetics being the transmission mechanism for individuals. So, the statement that Mendel's work "raises great obstacles" to evolutionary theory is simply ignorant and misleading.
Mendelian genetics support evolutionary theory in every way.
Actually, it doesn't. Darwin was unaware of Mendel's theory when he wrote his theory of Evolution (even though they lived at the same time), and because of the strong belief in Darwin's ideas it was not until the early 20'th century that the importance of the Mendelian theory was realized.
The Mendelian theory - because it showed that genes are own entities - raises great obstacles for the Darwinian theory. Natural selection operates on the organism level, rather than the gene level (the whole organism dies, if only one single fatal mutation occurs), which will mean that all the "good" mutations that need to add up during long time will get lost due only to a small number of fatal mutations, which makes it even more impossible for natural selection to give rise to something new which needs adding up of "good mutations".
The concept of "good mutations" - mutations that will be good only when many such mutations have been added together - is itself an erroneous way of thinking, because it builds on teleological reasoning (things get their "meaning" only after something has happened and you see the result) rather than causal reasoning ("cause gives effect"). Teleological reasoning is not rational in a naturalistic framework, because the only thing there is in such a framework is "cause gives effect".
There are alternate versions of a gene.
Natural selection is when biological organisms with favorable traits survive and reproduce more successfully than organisms that do not possess such traits. Organisms with negative or less useful traits survive and reproduce less successfully than organisms lacking such harmful traits. Natural selection played a huge part in the evolution of the great barracuda. The barracuda had to adapt their distinctive shape, design, and skills over the years and did so through many generations.
How do insecticides force evolution?
Widespread use of insecticides can lead to the evolution of insecticide resistance.
In any population of insects there will be genetic variation ie individual insects are not identical; just like humans there are all different. Some individual insects will be more resistant to an insecticide than others.
When an insecticide is used the individuals which are resistant will have a better chance of surviving. They will then pass on their resistance genes to their offspring, which will in turn have a better chance of surviving. In this way the resistance genes will spread through the population.
This is an example of natural selection in action.

Evolutionary psychologists would be most likely to predict that?
children are more likely to be valued by their biological fathers than by their stepfathers.
Theories of thromboangitis obliternas?
It is thought that Thromoboangitis Obliterans is an autoimmune disease. It as originally noted in 1879 by von Winiwarter, who was a scientist and doctor.
The principal point of the Darwinian theory of evolution by natural selection was that?
Charles Darwin introduced his theory of evolution by natural selection in 1859 as explanation for adaptation and speciation. It was stated that, "principle by which each slight variation, if useful, is preserved."
Evolutionists themselves would find the asking of the question offensive, although if they are honest they will admit that there have been a number of frauds committed in the name of evolution. Ernst Haeckel produced fraudulent drawings in favor of his theory of embryonic recapitulation, otherwise known as the biogentic law. Unfortunately this fraudulent theory, and particularly his fraudulent drawings continued to be reproduced in science textbooks until recent times.
Piltdown Man, Nebraska Man (a pig's tooth) and the Peppered Moths would be other well-known ones.
Others would refer to making unwarranted conclusions from speculative or inconclusive data. Another problematical issue is the equating of the theory of evolution with the law of gravity as if they are identical which they clearly are not. Other such 'term switching' confuses the issue and gives more credence to the theory than is warranted by the facts. Evidence which contradicts the theory is also consistently ignored. Whether the theory is true or not is a somewhat different issue from the use of such terminology which implies deliberate deception. Although this undoubtedly applied to Ernst Haeckel and also the Peppered Moths (these were fraudulently pinned to trees where they do not normally rest) as well as Piltdown Man, it is not applicable to any who push something they sincerely believe in.
AnswerEvolution as a fact and as a theory is not a deceit in any way.As pointed out, there have been instances of misleading; people tried to fabricate evidence at a time when not much was available. However, this does not lessen the validity of the mountain of other evidences already gathered then and since.
It is also noteworthy to point out many of these fraudulent examples actually do have relevance, albeit not in the overamplified and mistaken ways previously given.
they are still taught today as examples of both bad science and of exaggerated ideas.
Much "evidence" against the theory is rather deceitful itself, and such might be included under the heading of 'deceit in evolution'. Such 'evidence' includes claims of violating the second law of thermodynamics or of requiring an older earth than is possible. Neither is substantiated by the facts, and both examples have been debunked as valid criticisms.
Some small groups have personal views which hold that since some other (normally religious) belief is true to them, anything of the opposite nature or which contradicts this must needs be a lie or untruth - in this case, their beliefs lead them to label evolution as a deceit.
Such beliefs do not alter the evidence and support, regardless of how much they want evolution to be false.
Does Evolution affect climate?
The word "evolution" means "change". The Theory of Evolution is concerned with change among living things, animals and plants. Such change does not affect climate in any significant way. Earth is also evolving. The tectonic plates are moving; volcanic action is changing the face of the Earth, creating new islands, changing the topography. These changes---the evolution of Earth---do affect climate.
What is Charles Darwin is famous for?
On Origin of Species is his most famous work, and this is the book most commonly discussed when speaking about Darwin.
He had several books however, some of which were fairly controversial.
FAD stands for Flavin Adenine Dinucleotide, a coenzyme that plays a crucial role in carrying out redox reactions in cellular metabolism. FAD accepts and donates electrons during these reactions, aiding in the production of ATP, the cell's main energy currency.
What dangers might travelers face in the devonian period?
A traveler should watch out for armored placoderms. If the traveler is in the Early Devonian, these fish did not have teeth, but plates in their jaws that acted as teeth. By the late Devonian though, they had developed jaws that could measure up to 33 ft. The only thing a traveler should worry about on land is insects, because no other animals existed during this period. The traveler should watch out if they are visiting the Late Devonian because of the high levels of carbon dioxide in the atmosphere, colder temperatures, and meteorites striking the earth,
