Diversity

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.

They must help the organism in it'senvironmentso it may survive andreproduceand pass the trait down. If the trait is undesirable or useless the trait is selected against. Like if the desert was covered in snow, and all the 'prey' animals were out and wondering around. They can see if a 'predator' is coming, because of their orange-light brown color cause it doesn't blend in with the surrounding it isn't goodcamouflage.

you must got merhzad as yo teacher for biology . i dnt knoe the answer neither .

Here are a couple of possiblilties (there are more): * The population can develop isolated subpopulations on its periphery. Evolution is much more rapid in small isolated populations. * Changes in the environment can lead to rapid evolution. Variation that was once neutral may now become beneficial and increase in frequency, while variation that may have been adaptive in the previous environment may now be deleterious and selected against.

Intelligence is merely a property of some lifeforms. It has no direct relationship to evolution and can say nothing either way, although the apparent development of intelligence combined with otehr mechanisms (e.g. suitability, usefulness) may be considered evidence.

It is NOT scientifically disputed as the overwhelming number of scientists accept evolutionary theory. Those scientists, and others, that do not accept the theory do so for religiously ideological reasons, though they try to rationalize this by pseudo scientific proposals.

Fossils give a record as to what organisms lived throughout different time periods. Generally speaking, the lower layers of soil show the oldest fossils, which aids scientists in following the progression of evolution of an organism. Also, radioactive carbon dating is used in dating how old a fossil is by finding the amount of carbon^14, and then calculating how many half lives have passed to reach this amount.

A cDNA (complementary DNA) library is a DNA library that has been created from mRNAs that are present in the cell. Since a cDNA is created from mRNA transcripts, that means that in Eukaryotic organisms there will be no introns or transcriptional factors present in the cDNA library, only exons. Only protein coding regions will be present in a cDNA library. This also means that a cDNA library is often times tissue specific. Since the expression of mRNAs will be different in different tissues of the organism it will appear different then a genomic library. Often times to offset this problem a cDNA library will be composed of different tissues (brain, liver, heart) to encompass a greater variety of the proteins that are expressed. A genomic library will contain all the exons, introns, and transcriptional factors that are not found in the cDNA library.

cDNA library does contain exons, which is the protein coding regions.

A mechanism (most common) of natural selection where overall genetic diversity decreases due to particular trait or genotype getting 'fixed' into the population. It is usually represented as a parabola on a graph.

Evolution is the process of deriving species from other species, forms from other forms.

Homologous structures are structures in organisms that share the same components. A good example is the vertebrate limb - it's clear that our arm, a bat's wing, a dolphin's flipper and a mole's digging paw all share the same identifiable bones. This supports the idea they're all derived from a structure in a common ancestor, as opposed to being created independently.

when a computer is designed that will be able to design a computer more advanced than itself then we will have crossed the line and computer evolution will be quicker than our own

Sceptile.

FOR ME IT ONLY WORKED WHEN I PUT IT INTO THE SAME AREA AS THE ROMS ON MY MICRO SD CARD, NOT WHERE IT SAYS TO PUT IT ...I.E IN THE ROOT FILE

Evolution is simply the generation of diversity and the shaping of the diversity by environmental selection. Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The only progressive trend in evolution seems to be that more and more complex body designs have emerged over time.

In fact, one of the simplest life forms like bacteria - inhabit the most inhospitable habitats like hot springs, deep-sea thermal vents and the ice in Antarctica.

This is the reason why evolution in not equated with progress.

It allows different parts of the body to become specialized in different ways. This is called cephalization.

Key finds, especially if they are rare specimen, are not usually themselves put on public display. Rather, casts are made and distributed to researchers and musea around the world, while the fossils themselves are kept secure in laboratoria and archives, in a controlled climate.

Casts of Tiktaalik may be found in various natural history musea, such as the Harvard Museum of Natural History.

Evolution is simply genetic change within a poulation. That change can occur in several ways. One is immigration/emigration: individuals moving in or out of a population bring in or take out their alleles with them. Another is genetic drift, or chance events which cause the frequencies of alleles in a population to fluctuate. New mutations can change the allelic frequency as well. Finally, natural selection can cause some alleles to become more common at the expense of others. In short, natural selection is one of several mechanisms that can bring about evolution.

the actions of organisms as they use or fail to use body structures.

There isn't, of course, a gap in time. There are, however, very few fossils intermediate between simple stromatolites (the first more or less multicellular organisms) and the first complex organisms found just before the Cambrian Explosion. This gap most likely exists because while predation already existed (organisms consuming other organisms), no organisms had yet developed an internal or external skeleton that could have been preserved at death. The very few organisms from that era that were preserved despite of this, were preserved in the form of molds and casts.

Practice Hypothesis- playing is a type of learning that allows animals to perfect behaviors needed in functional circumstances, such as a kitten stalking brothers and sisters which it will do later in life.

Exercise Hypothesis- playing keeps muscular and cardiovascular systems in top conditions, esp. when young aren't doing strenuous activity to keep active. Recent studies, however, have shown that beluga whales and multiple dolphin species play as adults, at least when in captivity.
