The hypothesis that all modern humans descended from an African lineage is supported by the mitochondrial DNA evidence. The Eve hypothesis is the hypothesis that is based on the study of mirtochodrial DNA; that modern humans have a common female ancestor who lived in Africa around 200,000 years ago. It is also called African Eve hypothesis.
Answer:
A
Explanation:
The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.
Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
Answer:
Option 2.
Explanation:
The fossil proof for the human-chimpanzee last common ancestor (LCA) is rare and scarce due to: These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.
Fossil monkeys and prosimians were rare in the Miocene, however, apps were normal and dominant. Option 1 is inaccurate.
The majority of the apps known from the mid-Miocene are Old World monkeys, who are from an unexpected Linnaean family in comparison to we are is an incorrect statement so it is inaccurate.
The LCA lived in the Paleocene, a time from which we have got a number of the fossil record. so Option 3 is incorrect
Thus, the correct answer is - These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.
