Evolution

Theories in science are supported by evidence and not ' proved. ' That said, one would think that the variation in the sexes mating stratagies would offer some strong cross cultural evidence.

The application of dichlorodiphenyltrichloroethane (DDT) is considered the original event that resulted in the evolution of pesticide resistance in some insects. The incident numbers among the pivotal events in the twentieth century since its first applications date to the 1940s. Immunity to the pesticide's toxic effects may be traced back to as early as 1947.

If its environment merited them to need short legs or short legs made them survive longer, then a species would evolve short legs.

A Mimicry Adaptation

co-adaption

Can mate with other individuals of their species and have viable progeny.

Wastage does not kill you. Not having enough to survive does.

Those organisms that overproduce in normal times will produce barely enough in less fortunate times; those that can only produce enough in normal times will not produce enough in lesser times, and die off.

Directional Selection

the barriers that allow for more specific sexual preferences. such as leather or whipped cream, or in some species handcuffs.

Isolation and time.

The fundamental difference is that evolutionary theory is a purely natural, scientific account of the origin and multiplication of all species. It does not need a supernatural creator. It is based on evidence and reason and changes as new discoveries are made.

Genesis is an account in which a supernatural being creates animals, plants and humans in a short period of time ie 7 "days". Since the account is said to be inspired by the creator it cannot be changed by anything discovered since it was written.

If that variation is selected on the basis of survivability and reproductive success then the populations gene pool allele frequency changes and the population becomes better adapted to the immediate environment, or adapted to a new and changing environment.

Low genetic diversity can make a species more vulnerable to diseases, environmental changes, and reduced ability to adapt to new conditions. Inbreeding and genetic disorders are also more likely in populations with low genetic diversity.

If it produces milk-drinking babies. The only mammal that lays eggs is a platypus, it lays milk drinking babies I assume.

The smallest unit that can evolve is the population, not the individual. In other words, you can't evolve, but over generations, the population can be subject to natural selection and different traits can be selected. In addition, the evolution of a population will take generations of fluctuating gene frequencies, something you can't just watch in action. Of course, the speed of evolution is entirely dependent on the environment; some populations will evolve quicker than others.

It doesn't. Evolution is explained by population genetics, evolutionary theory.

Lamarck knew evolution was happening, his inaccuracies are in how he explained it.

The first part of his theory is known as "use it or lose it" today. He said that use makes organs and structures bigger or more useful. Giraffes needed long necks, while blind cave fish lost their eyes. Darwin thought this idea was too simple, and replaced it with natural and sexual selection.

The second major point Lamarck made was called acquired inherited traits. This means that traits that an organisms gets after it was born affects its offspring. This would mean that a bodybuilder would naturally get buff children, and that crabs that lost their claws would have clawless spawn. A famous experiment involving the mutilation of mice (which left their offspring unaffected) disproved this.

Because of our knowledge of genetics, we say that variation is caused by mutations and not acquired traits.
