Tossup
Description acceptable. This process is driven primarily by abiotic forces like climate rather than biotic competition according to the court jester hypothesis. One model of this process likens it to a ring and is exemplified by Larus gulls having a range that circles the North Pole. Darwin’s finches are often cited as exhibiting a rapid degree of this process due to adaptive radiation. One form of this process occurs when physical barriers block gene flow. Whether this process occurs among isolated populations or in one location differentiates its “allopatric” and “sympatric” mechanisms. For 10 points, name this evolutionary process of forming a new taxonomic unit more granular than a genus. ■END■
ANSWER: speciation [accept descriptions of forming new species; accept ring species; accept sympatric speciation; accept allopatric speciation; prompt on diversification or word forms like diversifying; prompt on evolution or word forms like evolving until “evolutionary” is read; prompt on adaptive radiation or evolutionary radiation until “radiation” is read]
