Do humans exhibit r-selected or K-selected species patterns? What will be an ideal response?
Humans exhibit almost exclusively K-selected species patterns. We have long development, later
reproduction, few young per breeding episode, long life span, and high parental investment. The only
question is if we are approaching the carrying capacity like a K-selected species, or exceeding it like
an r-selected species.
