Evolutionary analysis ch. 2 question n answers graded A+ 2023Lamarck - correct answer in 1809 that all species are derived from gradual evolution. He guessed it was driven by the inheritance of acquired traits. Said simple life forms are spontaneously generated from nonliving matter. His ideas were popular until the 1930s Vestigial structure - correct answer remnant of a structure that may have had an important function in a species' ancestors, but has no clear function in the modern species Law of succession - correct answer the general pattern of correspondence between fossil and living forms from the same locale Archaeopteryx - correct answer transitional form that has fully modern feathers and a dinosaurian skeleton Ring species - correct answer evidence where one species splits into two. ex. Greenish warblers with different songs inbreed wherever they meet except central Siberia homology - correct answer Similarity in characteristics resulting from a shared ancestry. molecular homology - correct answer with a few exceptions, all organisms use the same nucleotide triplet coons to specify the same amino acids o be incorporated into proteins processed pseudogenes - correct answer nonfunctional copies of nomal genes that originate when processed mRNAs are accidentally reverse transcribed and inserted at a new location. Easily distinguished because they lack both introns and promoters retrotransposons - correct answer retrovirus-like genetic elements that jump from place to place in the genome via transcription to DNA and insertion at a new site. Some encode functional reverse transcriptase
