Look at the use of fossils to support revolutionary theory: a scientist says that one organism (now a fossil; let?s call this organism ?A?) from x number of years ago is the ancestor of another organism (now a fossil; let?s call this organism ?B?) from x ? y number of years ago. But unless both organisms were observed when they were alive, and their progeny were observed, you cannot say that B is of the same lineage of A, no matter how similar they are. Use common sense, and you can easily see why this is true.
?Well what about genetic evidence??, you might say. It?s the same general principle. Those that claim that genetic similarity between species implies relation are wrong. It?s a fundamental logical fallacy to make that assumption. To use a metaphor, just because two computer applications have similar code and structures doesn?t mean that one app is a new version of the other. They could be written by the same programmer, and/or written in the same programming language. They could be very similar indeed (especially to someone who doesn?t know programming that well), but still be completely independently created programs.
Morphological similarities- same exact thing. Families and trees are artificial groupings based on morphological similarities, and morphological similarities, again, do not prove relationship between species. You cannot say A and B are related just because they are similar in features.
Evolution is completely based on a bad foundation. Evolutionists (yes, I can use that word if you?re going to call me a ?creationist?) really like to complicate the issue by adding complex theories on top and pointing to various papers and studies done. But when buying a building, do you look at the rest of the building if the foundation is bad? No, the foundation is essential to the integrity of the entire building. Evolution is entirely based on a false assumption, and the type of evolution that we are talking about here, macroevolution, has never been observed, PERIOD. Microevolution has been observed, but that is really genetic variation within a type of organism, and really is just a form of adaptation. You never see (or will see) a monkey turn into a human, or a human evolve into something that isn?t a human (unless scientists decide to play God and mess around with human DNA, but that is something else entirely, which requires intelligence, and not randomness).
"Homology: The word homologous is from the Ancient Greek for 'agree'- ?µ????e??, eg. homologous chromosomes 'agree' with each other.
In genetics, homology is measured by comparing protein or DNA sequences. Two homologous genes share a high sequence identity or similarity, supporting the hypothesis that they share a common ancestor. Sequence homology may also indicate common function. Sequence regions that are homologous may also be called conserved. Homologous sequences can be classified into two subtypes: orthologous or paralogous.
In evolutionary biology, Homology is used to describe structures that are alike due to common ancestry." - Wikipedia
