disruptive selection
Some individual organisms are better equipped to live and reproduce in their environment than others. If what makes them better equipped is heritable, their offspring will be more numerous and will tend to inherit the same traits or qualities themselves. The opposite will happen to those poorly equipped. They will have fewer or no offspring, and their negative traits will tend to disappear from the population as time goes on. These two tendencies are called positive (natural) selection and negative (natural) selection respectively. Natural selection is always relative to the environment. What is advantageous in one environment may not be so in another, and what is disadvantageous (deleterious) in one environment may not be so in another.

Here is a quote: "The relationship between adaptation and natural selection does not go both ways. Whereas greater relative adaptation leads to natural selection, natural selection does not necessarily lead to greater adaptation." I do not recall who said it, but this is what the relationship between both is. Here is a quote: "The relationship between adaptation and natural selection does not go both ways.

It will determine the speed, reliability and relative security of the transmission.
The environment, of course. A stable environment and there is no selection pressure on the organism so stasis results. ( according to punctuated equilibrium )

The cause of natural selection is a change in the environment of a species. This change can have many causes. E.g. climate change, introduction of a new species, flooding, etc. When such an environmental change occurs, the individuals which are the most fit will have the biggest probability to survive and change the relative gene frequency in a species' genetic pool.

Cast Away Travel and Carnival both offer a limited selection of nudist cruises. Due to the relative lack of interest for these types of cruises, tickets can be very expensive.
electron = relative charge = 1- relative mass = 1/1840 proton = relative charge = 1+ relative mass = 1 neutron = relative charge = 0 relative mass = 1
