The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from The Voyage of the Beagle by Charles Darwin: of a region where the jaguar and puma range over the
plains, less than 2.5 degs. from arborescent grasses, and
(looking to the westward in the same hemisphere) less than
2 degs. from orchideous parasites, and within a single degree
of tree-ferns!
These facts are of high geological interest with respect to
the climate of the northern hemisphere at the period when
boulders were transported. I will not here detail how simply
the theory of icebergs being charged with fragments of rock,
explain the origin and position of the gigantic boulders of
eastern Tierra del Fuego, on the high plain of Santa Cruz,
