Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:
1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.
2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.
