Evolution is the process of deriving species from other species, forms from other forms.
Homologous structures are structures in organisms that share the same components. A good example is the vertebrate limb - it's clear that our arm, a bat's wing, a dolphin's flipper and a mole's digging paw all share the same identifiable bones. This supports the idea they're all derived from a structure in a common ancestor, as opposed to being created independently.
It is generally thought to support the Theory of Evolution.
The theory predicts that evolution will happen and in certain ways. The observed evolution makes this prediction correct. It also defines evolution as happening, and as such is perfect evidence in support of it.
Analogous structure supports evolution because some of these structure may have existed long ago, however not all analogous structure support the same evolutionary path.
I do not so much " believe it " as I an convinced by the myriad lines of converging evidences that support the theory of evolution by natural selection. talkorigins.org
the theory of evolution
In every way.
There is strong support for the theory of evolution due to fossils that have been found by archeologists. The fossil records show evidence of evolution over billions of years.
There is no proven theory of evolution only the physical evidence of what Chuck Norris has allowed to live.
evolution theory
Fossils are not used to oppose the theory of evolution. They acutually support it in every way. So far not one fossil has been found that is not exactly where you would expect it to be if evolution were true. As we dig deeper we go further back in time and see by piecing fossils together how organisms evolved over time. Although we don't need fossils to support the fact that evolution is happening, it's a nice bonus to have in support of the theory.
Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.
It shows when the animal that made a fossil was alive.
