Convergent evolution refers to the development of similar traits in two species

Question

Convergent evolution refers to the development of similar traits in two species separated geographically who do not share a common ancestor that did provide initial commonalties. ____ Cladistics is the grouping of species or other taxa by their shared possession of characteristics that not present in the remote common ancestor. ____ Sinanthropus pekinensis was probably the victim of cannibalism. ____ Ardipithecus shows that bipedalism begins around 4.4MYA. ____ Homo habilis had a cranial capacity of between 500 and 800 cc. ____ Purgatorius is an early Eocene African hominin. ____ The first Homo erectus was found in Australia ___ The uprising of the Isthmus of Panama beginning about 3 million years ago precipitated Glaciations or Ice Ages. ____ Ice Man dates to c. 3, 500BCE and was mummified in a glacier. ____ Using mtDNA analysis researcher's have determined that modem humans left Africa 125.000 years ago and then again around 50,000 and 40,000 years ago and populated the world. ____ Although it is difficult to solve the nature/nurture issue regarding Alcoholism, a craving for alcohol may have a connection to monkeys searching for the most nutritious fruits, which are often fermented._ The Australopithecines had a slightly opposed great toe. ____ Homo erectus is associated with the Mousterian Tradition. ____ The Neanderthals seem to more regularly and deliberately bury their dead although there is slight evidence of burial practices before 250,000 BC. ____ Cave paintings are associated with the Upper Paleolithic. ____

Explanation / Answer

(1) True (convergent evolution is the process by which the organisms that are not closely related have shown to evolve similar traits as a result of having to adapt to similar environments)
(2) True (Cladistics is a method for classifying animals and plants having only those shared characteristics which can be deduced to have originated in the common ancestor of a group of species during evolution)
(3) False (Sinanthropus pekinensis itself was a cannibal)
(4) True (The earliest hominid with the most extensive evidence for bipedalism is the 4.4-million-year-old Ardipithecus ramidus)
(5) True (The Homo habilis brain capacity was around 640 cm³)
