In any weight reduction endeavor, it’s important to remember that the brain has two primary directives-TO SEEK PLEASURE AND SURVIVAL. Food is associated with both from years as a child. Associated with pleasure are what most call good emotions-happiness, pleasure, elation, and so on. Associated with success are what most call bad emotions-frustration, boredom, dilemma, anger, depression, and so forth. Unfortunately, most programs to lose deal or weight with winning concentrate on food and forget the emotional programming. Concentrating on what you do or do not eat to regulate or lose weight is like looking to fly by flapping your arms. Better to focus on the strain of the feeling whether it is frustration, happiness, upset, anger, pleasure, and figure out how to take it straight rather than diluting with food.

The bats are thus not assisting one another altruistically; they form pacts that are advantageous mutually. Helping closely related organisms can appear altruistic; but this is a selfish behavior also. Reproductive success (fitness) has two components; direct fitness and indirect fitness. Direct fitness is a measure of how many alleles, normally, a genotype contributes to the next generation’s gene pool by reproducing.

Indirect fitness is a measure of just how many alleles similar to its own it can help to enter the gene pool. Direct fitness plus indirect fitness are inclusive fitness. J. B. S. Haldane once remarked he would gladly drown, if in so doing he preserved two siblings or eight cousins. Each of his siblings would discuss one half his alleles; his cousins, one-eighth.

They could potentially add as much of his alleles to the gene pool as he could. Natural selection favors traits or actions that increase a genotype’s inclusive fitness. Related microorganisms talk about many of the same alleles Closely. In diploid species, siblings share on average at least 50% of their alleles.

The percentage is higher if the parents are related. So, assisting close relatives to reproduce gets an organism’s own alleles better displayed in the gene pool. The advantage of helping relatives increases significantly in highly inbred species. In some cases, organisms will forgo reproducing and only help their family members reproduce completely. Ants, and other social insects, have sterile castes that only serve the queen and assist her reproductive efforts. The sterile employees are reproducing by proxy.

The words selfish and altruistic have connotations in everyday use that biologists do not plan. Selfish simply means behaving so that one’s own inclusive fitness is maximized; altruistic means behaving in such a way that another’s fitness is increased at the trouble of ones’ own. Use of the words selfish and altruistic is not designed to imply organisms consciously understand their motives.

The opportunity for natural selection to use does not stimulate genetic variation to appear — selection only distinguishes between existing variants. Variation is not possible along every imaginable axis, so all possible adaptive solutions are not open to populations. To pick an absurd example somewhat, a steel shelled turtle might be a noticable difference over regular turtles. Turtles are killed quite a few by cars these days because when confronted with danger, they retreat into their shells — this isn’t a great strategy against a two-ton automobile.

However, there is absolutely no variation in metallic content of shells, so that it would not be possible to choose for a steel shelled turtle. This is a second example of natural selection. Geospiza fortis lives on the Galapagos islands along with fourteen other finch species. It feeds on the seed products of the place Tribulus cistoides, specializing on small seeds.
