Which observation is NOT an evidence for Darwin's theory of common descent?
Group of answer choices
There are biogeographic patterns in the distribution of species, for instance distinct bird species on an island tend to resemble.
Anatomical structures, such as forelimbs, in different groups appear to be modified versions of structures that might have been present in a common ancestor.
There are common stages in the early embryological development of organisms representing several distinct vertebrate groups.
Due to innate drive to improve, parts that are extensively used becomes larger and stronger and passed on to the next generation as seen on fossil records.

Place the statement in order of how they would occur in nature. Be thinking about natural selection.
Organisms produce more offspring than the environment can support.
Organisms that survive reproduce, sending their genes into the next generation.
Some organisms do not survive. Those that survive are better suited to the environment.
There is increased competition for resources.

Why are fruit flies good subjects with which to observe the process of evolution through natural selection?
Fruit flies are good subjects because they have very long generations, and scientists can control their development over long periods of time.
Fruit flies are good subjects because they have short generations and scientists can control their development in the lab.
Fruit flies change into different species of flies each generation, so they have more features to study.
Fruit flies are K-strategists, and these are easier to study over short periods of time.
