Kin selection is W.D. Hamilton's famous theory that explains altruism in nature. The theory is that the closer you are genetically related to someone the more altruistic you will be towards them. The ultimate goal in life is to pass down as many of your genes as possible and insuring that those genes survive to reproduce and pass them on to the next generation. What kin selection says is that you are more likely to be altruistic to you children (who share 50% of your DNA) than you are to be altruistic to you nieces or nephews (who only share 25% of your genes) and even less likely to be altruistic towards a stranger who shares 0% of your genes.

What is the relationship between kin selection and altruism in the context of evolutionary biology?
Kin selection is a theory in evolutionary biology that explains how altruistic behavior, where an individual helps others at a cost to itself, can evolve. Altruism towards close relatives, who share genes, can increase the chances of those genes being passed on, benefiting the overall genetic fitness of the family. This relationship between kin selection and altruism helps explain the evolution of selfless behavior in organisms.
How did evolutionary theory change?
The most important changes in evolutionary theory since Darwin's time are the inclusion of modern genetics and population genetics into the theory; the formulation of the punctuated equilibria model of evolution based on the mathematics of J. Haldane and others; the inclusion of models for kin selection and altruism throught the work of W. Hamilton and others; and the popularization of the gene-centered view of evolution, also mostly by W. Hamilton.

What does the term altrusim mean and how does it relate to kin selection?
Hamilton (1964) outlined two ways in which kin selection altruism could be favoured. Firstly, if individuals have the capacity to recognize kin (kin recognition) and to adjust their behaviour on the basis of kinship (kin discrimination), then the average relatedness of the recipients of altruism could be high enough for this to be favoured. Because of the facultative nature of this mechanism, it is generally regarded that kin recognition and discrimination are unimportant except among 'higher' forms of life (although there is some evidence for this mechanism among protozoa). A special case of the kin recognition/discrimination mechanism is the hypothetical 'green beard', where a gene for social behaviour also causes a distinctive phenotype that can be recognised by other carriers of the gene. Hamilton's discussion of greenbeard altruism serves as an illustration that relatedness is a matter of genetic similarity and that this similarity is not necessarily caused by genealogical closeness (kinship). Secondly, even indiscriminate altruism may be favoured in so-called viscous populations, i.e. those characterized by low rates or short ranges of dispersal. Here, social partners are typically genealogically-close kin, and so altruism may be able to flourish even in the absence of kin recognition and kin discrimination faculties. This suggests a rather general explanation for altruism. Directional selection will always favor those with higher rates of fecundity within a certain population. Social individuals can often ensure the survival their own kin by participating in, and following the rules of a group. from the web page encyclopedia.thefreedictionary.com/Kin+selection
What is the rule in biology about closed off organisms dying?
The rule in Biology about closed off organisms dying is known as Kin selection.
What is 'Kinism' and is it a biblically supported teaching?
Perhaps you can explain what Kinism or Kin is as it does not seem to be in the dictionary. Nor is it in the complete concordance of the bible.
What is the role of genes in kin recognition?
Answer 1Hard to answer as this is not settled in evolutionary biology. Some call this the " green beard effect, " where one organism's kin recognizes the organism by some physiological marker that is reflective of the genetic relatedness. Still, the evidence for this concept is rather thin, so we do not know if we are seeing such an effect, or one is just seeing the result of organisms being raised in close proximity.Answer 2There are various ways for genes to affect the recognition of kin. For instance, genes may affect pheromone production, giving the family member a recognizable scent. Genes might affect fur patterning, or bird-song. Certainly humans are often able to distinguish relatives by their facial features, even if they had not met these relatives before.Note that there is much still to be learned about the role of such genes in kin altruism, and that the mechanisms of kin altruism may not even need to rely on such outward markers. The subjects of kin recognition and kin altruism should, to some extent, be studied individually.
Can you use kin one cases for kin onem?
Yes you can use kin one cases for kin onem. The difference between the kin one and the kin one m is not the size or shape. It is that there is no loop or the dot on kin onem
