At the beginning of the
spring, Dr. Allan notices that there is an equal distribution of long and
short stemmed buttercups in the vacant lot (which is never cut) across the
street from his house, as well as in his own backyard. By the end of

lot, but mostly short stemmed buttercups in his yard, which he regularly
mows. These observations are examples of what biological
principle? Develop a hypothesis to explain Dr. Allan’s observations.
