Natural abundances vary based on the planet and its formation history. For example, Mars and Earth have
different oxygen isotope ratios. It has been suggested that the moon was formed when a planet-sized object
struck a glancing blow on Earth. Although the cores remained largely intact, the remnants of these two bodies
eventually reformed into Earth and moon. Explain how you could use isotopic analysis to support this theory.

Examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. examine the two squirrel populations in the accompanying figure. the populations are separated by a geographic barrier. if after a long period of time the two species are no longer separated, what evidence is needed to determine if speciation has occurred? the figure shows two populations of squirrels separated by a geographic barrier. polyploidy is creating new species. the two populations are not interbreeding freely. hybrid offspring of the two populations begin to appear. one species will increase into a population size twice as large as the other species.
