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.
