Evolution

1.) All organisms differ in traits such as size and behavior.

2.) No two individuals are exactly alike.

3.) There was a gradual change in each species.

4.) Fossils were different from the living animals. However, these fossils had many similarities to modern forms of life.

5.) Species on the Galapagos Islands resembled species on the mainland but they were different in certain characteristics.

6.) Some organisms became isolated on many islands.

7.) Most organisms produce more offspring that can survive

If I'm not mistaken the Law of Use and Disuse was disproved by August Weisman (scientist) several years after the death of Darwin (late 1800's). Weisman thought that if the law of use and disuse was true, he could prove it by cutting off the tails of mice for 20 generations in a row. No matter how many mice he cut the tail off of, the babies were born with a tail. His experiment proved that the law of use and disuse was false.

Devonian to cretaceous is the the geological age of ammonoids They first appeared during the Devonian Period (approximately 410 million years ago). They almost died out at the end of the Permian Period (251 million years ago), and again at the end of the Triassic Period (205 million years ago). They finally became extinct at the end of the Cretaceous Period (65 million years ago), perhaps as a result of a lowering of ocean levels.

What are other types of evidence for evolutionary theory, other than fossils?

Darwin's observations on the voyage of the Beagle, and succeeding scientist's observations that conform to his hypotheses. Domestication of plants and animals by purposeful and accidental selection over the past ten thousand years. Real-time observation of changes in bacteria, viruses and simple animals. A hundred years of fruit-fly experiments. DNA analysis and genetic decoding. The appearance of new stains of drug-resistant microbes comes quickly to mind. The breeding of animals for hunting and agricultural purposes, and for sporting purposes and pets, has been practiced for 1000s of years and is essentially human-directed evolution, and in many cases is historically documented. The principals of getting a good goat or cow were known and practiced long before anybody thought to extrapolate them backwards to the origin of a species and call it a scientific theory.

Birds are more closely related to reptiles than they are to mammals. Birds, reptiles, and mammals all belong to a group of vertebrates called amniotes, which split off from amphibians. Amniotes split into two groups soon after they evolved: true reptiles and synapsids. Mammals are the only living synapsids today. Dinosaurs branched off from the reptiles and birds then evolved from the dinosaurs.

Actually, all the religious people believed God created this world, and put them on this world for a reason. They believed that they had purpose in life.

But when Charles Darwin came along and said that we're related to monkeys, people got very upset. BEcause if you question one part of the bible, you're questiong the entire bible, and that's what Darwin did.

After he released his book, people found it upsetting to know that we are here by chance, and that we don't actually have a purpose on earth.

but honestly, if that's teh case, then we should be happy we're here by chance and live it up while it lasts.

Stabilizing Selection-- The extremes are selected against.Example: height; mostly beings tend to the average height- not too many really short ones or really tall ones.Directional selection-- One extreme value is selected for.Example: speed; faster is always better so a population will tend to get faster over time.Disruptive selection-- The extremes are both selected for.This type of selection is not as common as the first two. Example: Prey-type animal with distinctive markings which the predators know will over time move away from the norm in both directions.

Geographical Distribution of living species supports evolution because, as species are split up along the planet, they endure changes which better help they adapt to their surroundings. An example of this is with the Finches in Darwin's studies on the Galapagos islands. They all came from the same breed of finch but branched off with different characteristics to survive on the different islands that they were surviving on.

Punctuated Equilibrium, I believe is the answer.

Sexual selection is a concept that can be considered a subset of natural selection. In sexual selection, only the traits that lead to mating success will be passed on to the next generation. In other words, only the males with certain characteristics (most often strength and physical attractiveness) will have the opportunity to mate with the females and pass on their genetic information. Certain males are chosen by the females if they are considered to have superior genetic characteristics that will ensure optimal fitness for their offspring. Thus, the weak or unattractive males will not be able to reproduce.

Mating rituals vary throughout the animal species, but they often include competition between the males and physical displays. Sometimes, in social animals who live in groups, the alpha male who has proven himself to be superior to the other males of the group will be the only one who is allowed to mate with the females.

Sexual selection has resulted in the physical dimorphism between males and females of many species. Males sometimes have larger, more exaggerated, or more colorful physical characteristics, in order to impress the females or for use in mating competitions. A prime example of sexual selection is found in the peafowl. Only the male peacocks have the bright, blue-green plumage that is used to attract female mates. Female peahens have no use for them, so they are a dull brown or grey color.

There are two general categories of reproductive isolating mechanisms: prezygotic, or those that take effect before fertilization, and postzygotic, those that take effect afterward. Prezygotic RIMs prevent the formation of hybrids between members of different populations through ecological, temporal, ethological (behavioral), mechanical, and gametic isolation.

Yes, wolves play a crucial role in ecosystems by helping maintain populations of prey species in balance. They also impact vegetation, scavenger populations, and other predators within their habitat. Throughout their evolutionary history, wolves have become an integral part of various ecosystems worldwide.

criminological theory

Well, our existence. That's one.

Orgasms, that's a product of evolution. Happiness, joy, the instinct to help one another, those are all products of natural selection.

We also use evolution to fight against diseases, predict how they're going to change and so on.

Evolution also ensures that the various changing ecosystems in the world don't come crashing to a halt and cut short our food supply, that's nice.

If you mean our continued evolution, we're getting smarter (though at a depressingly slow rate), taller, and we're adapting to changes in our diets.

I assume you mean the trial in 1925 Tennessee that had John Scopes as the defendant for teaching evolution in violation of the law at that time.

Things that do not contribute greatly to evolution include individual organism's desires or needs, acquired traits during an organism's lifetime, and random or chance events (such as mutations that do not confer a survival advantage).

When a mutation occurs in the replication process, it changes certain features, like maybe better eyesight, and maybe bigger eyes, or bigger claws, and the meaning of evolution is when something changes into a better form.

It merely increases biodiversity. For example if twenty dinosaurs existed only and ten migrated to a completely different habitat the migrants would either go extinct or change so much they would seem like a new species. So, evolution makes biodiversity even more diverse than it is, only if the species don't go extinct.
