Question 6 of 10 4.0 Points Organisms with life histories that involve very short pre-reproductive periods, many offspring (produced even at a risk to parental survival), and little parental care have very high potential rates of population growth. From this perspective humans seem particularly un-fit. How can life histories with long pre-reproductive periods, few offspring, and lots of parental care persist?

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.
