body size or composition to enable comparison
between individuals.

size, distance from the mainland, maximum sea depth
between the mainland and the islands, and latitude relate to
body size in the treeshrew populations.
Maximum sea depth
between the mainland and islands was a secondary driver of
body size, with treeshrews on islands separated from the mainland by deeper waters typically exhibiting larger
body size, the researchers said.

In the mid-1970s, two groups of astrophysicists independently proposed that the moon was formed by a grazing collision
between a Mars -
sized body and the proto - Earth.
The simulations suggest that planetary
bodies the
size of the moon existed prior to the creation of the earliest chondrules, and that it was the enormous pressures produced by a collision
between two such
bodies that were responsible for the formation of the glassy spheres.
To get a better sense of the role of chondrules in a fledgling solar system, the researchers first simulated collisions
between protoplanets — rocky
