C. Ease of transporting food. The waters are inhabited by creatures deadly to apes and humans, such as crocodiles and hippopotami. Organisms that occasionally support their weight on two hind legs, such as when fighting, foraging, copulating, or eating, are said to exhibit limited bipedalism. Information Technology Project Management: Providing Measurable Organizational Value, Claudia Bienias Gilbertson, Debra Gentene, Mark W Lehman, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer. Increased Cost. B. Australopithecus afarensis Organisms that habitually walk on two feet are called habitual bipeds and inhabit terrestrial environments. What true information could you tell her to try to convince her not to have surgery? Although you don't find any leg bones or pelvis, you are able to definitively say that this fossil came from a bipedal hominin because of: Long before we used our hands to text on phones while walking, our hominin ancestors used their free hands to carry tools and even infants (as human babies cannot cling to their mothers). Longer hind limbs for clinging and leaping. One of the primary benefits of bipedalism is that it allows an organism to free up its hands to perform tasks like carrying food or tools, or using them to defend against predators. The earliest chipped stone tools are generally called __1__ and the earliest of these tools date to about __2__ mya. Two homes are identical, except that the walls of one house consist of 200200200-mm lightweight concrete blocks, 202020-mm\mathrm{mm}mm airspace, and 202020 - mm\mathrm{mm}mm plasterboard, while the walls of the other house involve the standard RRR-2.4m2.C/W2.4 \mathrm{~m}^2 . Nonetheless, both formats of therapy have advantages and disadvantages. A. There's going to be so much research that's stimulated by this paper." 2. program should ask the user to enter the charge for the food, and then calculate the amount The provisioning hypothesis proposed by __1__ focuses on the advantages of __2__ for the survival of the mother and offspring. Explain. There is compelling evidence that point towards climatic changes over long periods reduced forested areas forcing early hominins to get into habitual bipedalism allowing them to range into open landscapes. Their continued presence indicates that many australopithecine species likely spent significant time in the trees as well as on the ground. 1. Human walking is about 75% less costly than both quadrupedal and bipedal walking in chimpanzees. Brain Enlargement From observation, wild chimpanzees walk bipedally most of the time allowing them to carry and transport more items. C. It dates to 7-6 mya. True, Although there are many debates about the shape of the hominin family tree and particular lines of descent, scholars widely accept that the genus Homo evolved from Australopithecine ancestors.
