Which of the following statements is FALSE about the long-term evolution experiment (LTEE) that you learned about in the Case Study 2 content? a) The LTEE is different from most other studies of evolutionary change within lineages because the "frozen fossil record" allows recovery and further study of ancestors that lived many thousands of generations ago. Ob) The LTEE shows that the evolution of a new trait may occur in several steps, the first of which is the origin of mutations that arise because someday they will make it possible for new traits to manifest and be selected for in a given environment. Oc) The LTEE reinforces the notion that whether a given mutation is beneficial or deleterious depends on the environment in which the organism lives. O d) The LTEE shows that traits can evolve independently and even repeatedly, but that there are also signs of historical contingency in that they do not necessarily evolve in exactly the same way from a genetic standpoint. O e) The LTEE shows that although this is much more difficult in a historical science like evolutionary biology, lab experiments can be used to study evolution, as long as organisms with sufficiently fast generation times are used.

Transcribed Image Text:Which of the following statements is FALSE about the long-term evolution
experiment (LTEE) that you learned about in the Case Study 2 content?
a) The LTEE is different from most other studies of evolutionary change within
lineages because the "frozen fossil record" allows recovery and further study
of ancestors that lived many thousands of generations ago.
Ob) The LTEE shows that the evolution of a new trait may occur in several steps,
the first of which is the origin of mutations that arise because someday they
will make it possible for new traits to manifest and be selected for in a given
environment.
c) The LTEE reinforces the notion that whether a given mutation is beneficial or
deleterious depends on the environment in which the organism lives.
O d) The LTEE shows that traits can evolve independently and even repeatedly,
but that there are also signs of historical contingency in that they do not
necessarily evolve in exactly the same way from a genetic standpoint.
e) The LTEE shows that although this is much more difficult in a historical
science like evolutionary biology, lab experiments can be used to study
evolution, as long as organisms with sufficiently fast generation times are
used.
