Say you found another isolated pond about a mile from your first pond. This second isolated pond contains a population of 50,000 Danio kerri.

Physically they are very similar to each other, which leads scientist to think that when the Grand Canyon was shallower (millions of years ago) the populations use to have genetic contact (sexual reproduction). In present day, they are completely isolated from each other. When tested the Abert and Kaibab squirrels cannot produce a fertile offspring. This is an example of ___ speciation. [Fill in the blank]arrow_forwardResearchers discover two populations of monkey flower (Erythranthe) in Yellowstone National Park. One population is found near geysers and thrives near the hot water. The other population is found in the dry slopes of the mountains nearby. Both populations appear physically similar. Based solely on their observations, the researchers make an initial hypothesis that the two populations of Erythranthe are actually two separate species.
