** Added on to this idea is the idea of competitive altruism. Where organisms have to find the right balance between being cooperative and beinng choosy. If they are too cooperative than they can easily get taken advantage of. If they are too choosy then they won't be trusted because they barely help out.

** Memetics is the theory that ideas are alive just like organisms. While bacteria reproduce through dividing and many animals reproduce through sex ideas reproduce by getting their host to use language to implant them into another hosts brain. In theory they can do this even at the cost of genetic fitness to the host organism. For instance the Shakers of the 1800's were able to survive for a while despite one of their doctrines being that adherents can't ever reproduce. They did this by taking in the many orphans and widows of Victorian society.

Added DiffLines:


*Specific phenomena cited as mechanisms organisms can use to overcome nature's every organism for themselves free for all include kin selection, reciprocal altruism, and memetics.
**Kin Selection centers around the idea that genes are what's selected for instead of organisms. A gene competes not only with the genes in other organisms but also the other genes in the organism it is a part of. Most genes aren't present in a single organism though and are present across multiple organisms so it makes sense for the same genes in different organisms to cooperate with each other to increase their presence in the next generation.
**Reciprocal altruism is where one organism helps out another organism in exchange for help from that organism in the future. For instance if a monkey wasn't able to find food that day but other monkeys in the group found more than they need. The monkey with an excess can give some to the monkey who doesn't have any in the hopes that the monkey without any food will return the favor in the future when the monkey with an excess needs help. This can be seen as taking out an insurance policy for when times get rough.

The word "evolution" in its most basic terms simply means "change over time". In biological terms, it is the inheritance of genetic traits within populations of organisms through successive generations. Evolution is one of the most strongly supported scientific theories, and is in fact the cornerstone of modern biology.

* Firstly, the law actually states that entropy, a measure of randomness, cannot decrease in an '''isolated system'''--i.e., things in an isolated system tend to even out: hotter areas lose heat to cooler areas, friction takes energy from motion, and so on until the system achieves equilibrium. Hence, why there is no such thing as perpetual motion. However, biological processes take place in our planet, which is '''not''' an isolated system. Earth receives energy and material from the Sun and other space debris and phenomena, so applying this law to evolution as a whole is based on a faulty premise.
* Secondly, if the Earth actually was a closed system, then it is true that evolution would not happen--but neither would life in the first place. Life is just the distribution of energy from one lifeform to another in the form of several processes of conversion (photosynthesis, digestion, decomposition etc.), and that process would need a constant supply of energy or it would peter down to equilibrium instead of encouraging growth. The lowest rungs of most food (energy) chains usually begin with something requiring photosynthesis, which takes energy from an outside source, the Sun. Yes, some life does take its energy from geothermal energy, but that will eventually run down[[note]]Assuming that the Earth first doesn't get consumed when the Sun goes gigantic in its death throes or something large enough to affect the inner geothermal movements of Earth hits it[[/note]] as has already happened inside Mars.

* There are not "more evolved" (humans and apes) and "less evolved" (frogs, insects, plants) species. All living things are descended from a common ancestor, and have the same three or so billion years of evolution between then and now. (While species aren't more or less evolved, they can be more or less complex. Lineages can evolve from high to low complexity - think of lizards losing legs to become snakes.) If you really pressed an evolutionary biologist to pick "more evolved" organisms, they'd reason that natural selection is most effective with short generation times and large populations, and therefore choose bacteria.
