microevolution
The different populations in a community can interact in different kinds of relations with each other. Example include symbiosis, parasitism, commensalism, etc.
The great lakes is an example of a geographic barrier, isolating populations from each other. Populations can become separated (isolated) from one another, as one group expands northward of the lakes and another expands southward of the lakes. Mountain ranges are geographic barriers that isolate populations from one another, in much the same way as the great lakes. Oceans geographically isolate land masses, and their respective populations, from one another. This includes islands as well as continents. Examples: the Galapagos Islands, Madagascar, and Australia. *Geographic isolation is the chief mechanism of allopatric speciation, considered by some to be a theory.
it's better to explain it using an example. say there are two types of moths - black and white. the black allele and the white allele together make up the gene pool (all of the alleles together) for the moth species. then say that there are only black trees in the habitat of these moths. in the eyes of a predator, it is much easier to see the white moths on the black trees than the black ones, so they continually get eaten. therefore, the allele frequency of the white moths goes down. because the moths are being eaten and there are less and less of them, we say they are being selected against and eventually the white moths die off, because they are not adapted to their environment
1) The Life Cycle-- tracing the development of a baby from the fetus stage to old-age adulthood. 2) The genetic "evolution" of human natural selection that gives rises to the different "races" of people, which is really variations (with the emphasis on phenotypical variations) within human kind. There is nothing beyond this, as ameobas to man type of macro-evolution is not only a philosophical story, it is also not well supported scientifically. This belief is, therefore largely assumption and less scientific.
Be careful with this, it is usually misinterpreted as survival of fittest individuals. Instead it is survival of fittest population via death of some individuals early. Individuals never evolve, they are fixed genetic snapshots in the movie of life, they simply live or die. Populations evolve.
It is an example of continuous variations.
Different types of different populations obtain their food in a variety of ways. Fish for example swim to catch their food.

Attracks means to take an aggressive action against something. Typically it has to do with weapons. An example would be that "englands peasent's attracks wrecked havoic on the economy".

Colored is a verb when used in the sense of having, for example, colored something: She colored her hair red. Her child colored a drawing green. He colored his fence white. Colored is also a verb when used in the sense of blushing or changing color: He colored when he realized they knew he'd lied. The sky colored at dawn. Colored is an ajective when used in the sense of being a certain color: The curtains were colored blue. The new paint was red-colored. Their views are colored by recent media reports. Some foods are artificially colored. Colored is also a nearly-obsolete term for a person with skin darker than, for example, a light-skinned Caucasian person. This could be either a noun or an adjective: The terms 'colored person' 'person of color' or 'colored races' are now considered derogatory and offensive, and are no longer in general use' We would never now refer to anyone as 'a colored', as some might have a century ago.

Although food coloring can be used to color pasta, the better quality colorful pastas are colored with vegetables. For example, orange pasta may be colored with carrots or tomatoes, green pasta colored with spinach, and a bright magenta pasta colored with beets.
I colored and washed my hair today.
There are many types of parasitism in an estuary. For example, Griffen's isopod is a parasite that has destroyed mud shrimp populations in Northern California.
