If the stages of human evolution is written in descending order according to their cranial capacity then the correct order obtained is
A. Homo Habilis, Homo erectus,Homosapeins, Australopithecus
B. Australopithecus, Homo Habilis, Homo erectus,Homosapeins
C. Homosapeins, Homo erectus, Australopithecus, Homo Habilis
D. Homosapeins, Homo erectus, Homo Habilis, Australopithecus
Solution
Cranial capacity: the brain case's cubic capacity measured by a formula based on head measurements and calculated for the skull by filling the cranial cavity with particulate matter (as a mustard seed or small shot) and calculating the volume of the latter.
Complete Answer:
- Hominin brain expansion tracks so closely with tool technology refinements that some researchers neglect other factors that may have led to the growing size of the brain, such as social sophistication, foraging techniques, symbolic communication, and abilities that left no or little archaeological traces for other culture-mediated activities.
- The brain has continued to develop during human evolution. However, one must be highly careful about assigning higher cognitive capacities. Concerning approximate body mass, H. Habilis is "brainier" than H, in fact. H. and Rudolfensis Ergaster.
- Australopithecus is a hominid genus that is extinct. The Australopithecus genus apparently originated in eastern Africa around 4 million years ago, from paleontological and geological data.
- Homo habilis is a species of the Hominini tribe, between about 2.8 and 1.5 million years ago, during the Gelasian and early Calabrian periods of the Pleistocene epoch.
- Homo erectus is an extinct hominid species that lived throughout much of the geological period of the Pleistocene. The earliest fossil evidence is 1.9 million years old, with the oldest being 70,000 years ago.
Hominin | Number of fossil examples | Average capacity of the braincase (cc) |
---|---|---|
Australopithecus | 6 | 440 |
Paranthropus | 4 | 519 |
Homo habilis | 4 | 640 |
Javanese Homo erectus (Trinil and Sangiran) | 6 | 930 |
Chinese Homo erectus (Peking man) | 7 | 1,029 |
Homo sapiens | 7 | 1,350 |
Cranial ability is the brain's size. Although the newer human form has a larger and more sophisticated cranial ability, the older version has a smaller one. Homo sapiens sapiens, the present human being, the Neanderthal man, has a large cranial ability. And there's also a more evolved brain. This results in a greater capacity for thought for people of the present age.
Although there is a greater and more evolved cranial ability for the younger version of humans, older ones have a smaller one. Homo sapiens sapiens, the present human being, the Neanderthal man, has a large cranial ability. And there's also a more evolved brain. This results in a greater capacity for thought for people of the present age.
The correct Answer is option (D) Homosapeins, Homo erectus, Homo Habilis, Australopithecus.
Note: Brain development allowed hominids to create and use instruments and fire, to communicate using language, to establish culture and society, to adapt to new environments, and ultimately to become self-conscious and creative.
