natural selection. when organisms somehow inherit a trait that allows them to survive it is more likely that this trait will be passed on to offspring. the organisms without this trait will die and not be able to reproduce and therfore will not be able to make an undesirable trait more common. the trait that gives the advantage eventually becomes dominate and every young of the specific animal is born with the trait except for the few natural mutations that may occur. a good example of this would be how the length of the giraffe neck became common because of its advantages.
The fossil records of living things will often show how they appeared, and dating rock layers can estimate when the particular organism lived.
Study of change is called evolution .
Once an organism is named there is always the possibility that the name can be changed. Since organisms can evolve and change over time the properties that made the organism what it was originally may be no more and require a new name.
PHYLOGENY
The organism's evolutionary history. It tells how the organism has changed over time.
Any change in a type of organism over time is called evolution. It is the process by which modern organisms descended from prehistoric ones.
how the species evolved
By the process of natural variation and selection by survival of the fittest.
The evolution of a organism depends on what type of organism it is
Evolution is defined as a change in allele frequencies over time. Since individuals have only the set of alleles that they're born with, an individual cannot evolve. This leaves the population as the smallest unit that can evolve.

all of the organisms can evolve.

A change in an organism that takes place over time is called an adaptation. An adaptation happens when an organism needs to change in order to survive.
