What evidence do scientists need to show that observed changes are actually due to natural selection?
A) experimental manipulation of a population
B) statistical significance
C) notes and observations
D) detailed drawings of changes over time

Question

Quizplus · Accepted Answer

To confirm that observed changes are due to natural selection, scientists need to experimentally manipulate a population by introducing selective pressures under controlled conditions. This would allow them to observe if changes occur as expected due to natural selection. Statistical significance and notes/observations can support evidence of natural selection, but experimental manipulation is necessary for confirmation. Detailed drawings of changes over time can be helpful but are not essential evidence for natural selection.
