Which sequence accurately portrays the chronological order in which hominids evolved? . a. homo habilis, homo erectus, australopithecine, homo sapiens . b. homo sapiens, homo erectus, homo habilis, australopithecine . c. homo erectus, homo habilis, australopithecine, homo sapiens . d. australopithecine, homo habilis, homo erectus, homo sapiens .

Option D i.e Australopithecine, Homo Habilis, Homo Eructus, Homo Sapiens is the correct answer.

Australopithecine is the first form of human evolution and thus the first species to walk upright. He is followed by Homo Habilus which used his hands to make tools. Then it was followed by Homo-Eructus (human like body-proportions) which was followed by Homo-sapiens or Modern man.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
