Ecological niche modelling is used to predict the distributions of species. As a general rule, which of the following statements is true?

#Section 1: Ecology
  1. Distributions of species do not reflect the range of physical conditions that support the survival and reproduction of individuals
  2. The more suitable the conditions for a species, the denser its population, and the greater its productivity

  3. Changes over time in conditions such as temperature, precipitation, and salinity have not been shown to affect the distribution of marine fish species
  4. Global climate change always results in a decline in the number of species inhabiting a given area

The horizontal axis of the cladogram depicted below 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. Let's 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 pair of scientists below would probably have agreed with the process that is depicted by this tree?
