<span>If
a geological barrier (like a continent splitting apart) separates a
population of primates, then each population will evolve separately to
fit the different conditions of their environments.
As a hypothetical example, if one part of Pangea went north, the
primates on that part would adapt to cold temperatures. If the other
part went toward the equator, those primates would adapt to heat and
direct sunlight. Eventually they would evolve into different species
over many generations.</span>
The thing that makes kes73 interesting to astronomers is ; ( A ) A second star.
kes73 is believed by astronomers to have come from the explosion of dying stars in the supernova. The gases from the dying stars explode and scatter across forming a colorful cloud known as kes73.
At the center of the colorful cloud formed from the gases of the dying stars is a second star ( magnetar ) which is the most powerful star in the galaxy due to its magnetic force.
Hence we can conclude that the thing that makes kes73 interesting to astronomers is the presence of a second star
