Capitolo 82
one hundred miles from Hampshire Nuovo in Labrador, all of a sudden the
the same butterfly reappears, and it scatters toward the pole in toward north
great abundance. Now, as it made this small colony of cold bugs gets
separated by the principal body and islanded, as is, on a remote
the mountain-top in far more heat Hampshire Nuovo?
The answer is, they had stranded there at the end of the Glacial one
epoch.
A pair of one hundred thousand years ago or in the proximities--I/you/he/she don't do us
you dispute, I implore of you, during the course of some casual centuries--the whole one of
Northern Europe and America were covered by end to end, as each
he/she knows, from a sheet of solid ice as that that Frithiof Nansen
crossed by sea sea on his really account in Greenland. For many
thousand years, with warmer occasional spells that enormous ice-sheet
brooded, silent and surly, on the face of the two continents. Life was
extinct as far south as the latitude in New York and London. Nothing plant
or animal escaped the general congelation. Not a creature broke the
the monotony of that glacial desert and without end. Finally, as the celestial one
cycle entered round in due season, fresh it conditions supervened. More heat
time rose up, and the ice started to melt. Then the plants and animals
some make up for-glacial district was slowly inclined toward north from the heat
after the ice-beret that withdraws. As it followed time the climate of the,
plans found too much heats to hold them. The summer was too much for the
glacial types to bear. They only remained on the tallest mountain
peaks or next to the southern limit of eternal snow. In this way,
every isolated series in both continent has his proper small colony of
arctic or glacial plants and animals from which survive still
them, not influences subject from relationships with them unknown and
unsuspected individual-creatures elsewhere.
It not only has the Glacial epoch left these organic traces of his
existence, however; in of the parts of Hampshire Nuovo, where the glaciers
it was often unusually and deep, it fragments some primaeval him you freeze
