……………………………….. can be defined as “descent with modification from
a common ancestor”. We can call groups of organisms populations-
but when those groups of interbreeding populations form a single
“species”, we’re applying the……………………………….. Species concept,
conceived by……………………… (Last name only). When random forces affect
evolution, we call this…………………….. . When environmental or other
forces act to change gene frequency, we call this…………………. . We now
consider the unit of inheritance to be a…………………….. . So the study
of the process of speciation can be considered in a mathematical
framework, and we call this …………………….. genetics. ………………… (Last name
only) wrote extensively about this, and in your reading and in
class you have come to learn that he defined the statistics that we
use to study evolution.
