Question

question 4 1 pts which of the following reflects charles darwins key scientific theory? species evolved under the pressures of natural selection. that certain ethnic groups were more superior than others individuals passed on to their offspring traits they had acquired. the weak would dominate the strong.

Explanation:

Darwin's key scientific theory is evolution by natural selection. This theory states that species evolve over time as individuals with traits better suited to their environment are more likely to survive and reproduce, passing those traits on. The option "Species evolved under the pressures of natural selection" aligns with this. The other options are incorrect: ideas about ethnic group superiority are not part of Darwin's scientific theory (and are unethical and unscientific in a broader sense), the idea of passing on acquired traits is Lamarckian (not Darwinian), and "the weak would dominate the strong" is not a tenet of Darwin's theory.

Answer:

Species evolved under the pressures of natural selection.
