Misconceptions about evolution and the nature of science
Narrowly, it is defined as the proportion of variation (more strictly, variance) in a in a population that is due to individual genetic differences that will be inherited in the offspring.
Partly or wholly determined by genes; capable of being passed from an individual to its offspring.

It cannot be used to determine the age of Earth, for example.
From there one could straightforwardly calculate the approximate number of trials of new genes that could have occurred, during a reasonable time window, to produce an antifreeze protein gene in the fish.
The basic structural and functional unit of most living organisms.
Finally, a mathematician could, with little trouble, count the number of possible different genes that could be created from the trypsinogen gene and other possible precursor genes by the steps listed above.

CORRECTION: Though "survival of the fittest" is the catchphrase of natural selection, "survival of the fit enough" is more accurate. In most populations, organisms with many different genetic variations survive, reproduce, and leave offspring carrying their genes in the next generation. It is not simply the one or two "best" individuals in the population that pass their genes on to the next generation. This is apparent in the populations around us: for example, a plant may not have the genes to flourish in a drought, or a predator may not be quite fast enough to catch her prey every time she is hungry. These individuals may not be the "fittest" in the population, but they are "fit enough" to reproduce and pass their genes on to the next generation. To , visit our article on this topic.
