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.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
