What does the tea party have to do with this?

Don't get so ruffled. It's just a friendly discussion.
Hardly ruffled, just saddened that we live in a time of Dark Ages when myth and false religions try to erase everything since the Renaissance. This is an effort to suck up to religious nuts and the tea-monster. Europe must be laughing at us.

I really doubt you buy much of their crap but then you did like Wichita.

Evolution (or more specifically biological or organic evolution) is the change over time in one or more inherited traits found in populations of individuals.[1] Inherited traits are distinguishing characteristics, for example anatomical, biochemical or behavioural, that are passed on from one generation to the next. Evolution requires variation of inherited traits within a population. New variants of inherited traits can enter a population from outside populations, and this is referred to as gene flow.[2][3][4][5] Alternatively, new variants can come into being from within a population in at least three ways: mutation of DNA, epimutation (a change inherited in some way other than through the sequence of nucleotides in DNA), and genetic recombination. Natural selection, where different inherited traits cause different rates of survival and reproduction, can cause new variants to become common in a population.[1] Other evolutionary mechanisms can cause a variant to become common even if the variant does not directly cause improved survival or reproduction. These mechanisms include genetic hitchhiking, genetic drift,[6][7] and recurrent biased mutation or migration.
Evolution has led to the diversification of all living organisms from a common ancestor, which are described by Charles Darwin as "endless forms most beautiful and most wonderful".[8] For example, evolution is the cause of speciation, whereby a single ancestral species splits into two or more different species. Speciation is visible in anatomical, genetic and other similarities between groups of organisms, geographical distribution of related species, the fossil record and the recorded genetic changes in living organisms over many generations. Common descent stretches back over 3.5 billion years during which life has existed on earth.[9][10][11][12] Both evolution within populations and speciation between them are thought to occur in multiple ways such as slowly, steadily and gradually over time or rapidly from one long static state to another.
The scientific study of evolution began in the mid-nineteenth century, when research into the fossil record and the diversity of living organisms convinced most scientists that species evolve.[13] The mechanisms driving these changes remained unclear until the theory of natural selection was independently proposed by Charles Darwin and Alfred Wallace in 1858. In the early 20th century, Darwinian theories of evolution were combined with genetics, palaeontology and systematics, which culminated into a union of ideas known as the modern evolutionary synthesis.[14] The synthesis became a major principle of biology as it provided a coherent and unifying explanation for the history and diversity of life on Earth.[15][16][17]
Evolution is currently applied and studied in various areas within biology such as conservation biology, developmental biology, ecology, physiology, paleontology and medicine. Moreover, it has also made an impact on other disciplines such as agriculture, anthropology, philosophy and psychology. Evolutionary biologists document the fact that evolution occurs, and also develop and test theories that explain its causes.
