dN/dt = rN (K-N/K ) The logistic equation above is used to describe the rate of change of a population, N, with time, t, Where r is the intrinsic rate of increase and K is the carrying capacity. What is value of per capita growth rate when population size is 200 individuals? ( K= 400, r =.25)

The treeʹs horizontal axis is a timeline that extends from 100,000 years ago to the present; the vertical axis represents nothing in particular. The labeled branch points on the tree (V—Z) represent various common ancestors. Letʹs say that only since 50,000 years ago has there been enough variation between the lineages depicted here to separate them into distinct species, and only the tips of the lineages on this tree represent distinct species. Which of the five common ancestors, labeled V—Z, has been most successful in terms of the percent of its derived species that are extant?
