Document Summary

At the time, there was a worldwide belief of special creation. All species are independent and unrelated to one another. Earth is young (approximately 6,000 years old) 1) pattern component- observes about natural world using facts and explain how things are in nature. 2) process component- produces pattern and set of observations. Typological thinking- species are unchanging and variations are unimportant/ misleading. Transitional feature- an intermediate trait between an older and younger species https://evolutionnews. org/2018/07/from-bears-to-whales-a-difficult-transition/ Vestigial trait- reduced/ incompletely developed structure, may have no or reduced function. E. g. kiwis and ostriches have reduced wings and can"t fly https://thinkingscifi. wordpress. com/2011/10/03/vestigial-relics/ 1) genetic homology- studies dna nucleotides, rna nucleotide, or amino. 2) developmental homology- studies embryos and their similarities. E. g. chicks, cats, and humans all have tail structures called gill pouches as an embryo http://faculty. ycp. edu/~kkleiner/evolbio/evolbioimages/evidenceforevol/evidenceevol. h. 3) structural homology- adult morphology, formation tml. 4) individuals that produce most offspring allows survival of the species.
