Pre-Flood animals lived in a uniform climate (Talk.Origins)

Claim CH520:


 * The pre-Flood climate was uniform, allowing all animals to live not too far from Noah. There was no need for them to migrate across entire continents.

Source: No source given.

CreationWiki response:

It is interesting that Talk Origins does not give a source. This claim is made mainly by some advocates of the canopy theory.

Actually a need for some animals to "migrate across entire continents" is not a problem from The Genesis Flood, such migrations occur even today. Now it is likely that climate differences from pole to equator, were less extreme than today and there seems to have been only one supercontinent, but there still would have been different habitats and probably some degree of climate difference from pole to equator.

The Bible makes it clear in Genesis 7:9 that God sent the animals to Noah, as such they did not need to have originated in Noah's part of the world, since God could have directed them around or have removed any obstacle.

However Talk Origins arguments are still flawed.

Talk Origins is thinking in terms of modern species not the original kinds. They don't give any examples of whole genera or families going extinct because of the introduction of a new genus or family. Furthermore their examples are all of species being introduced from outside, not various genera and families naturally living in the same environment.

This is flawed because all of Talk Origins' examples:
 * Are species, not genera or families.
 * Deal with introducing new animals, not animals that naturally live together.
 * Based on modern degenerated varieties (species) of the original kind.

Once again Talk Origins is confusing species and kind. It ignores the fact that the different species are degenerated varieties of the original kinds and that most modern differences in biota are post Flood adaptations.

Once again Talk Origins is confusing species and kind. Furthermore these species are degenerated varieties of the original kinds as such the original kinds were not as sensitive to changes in temperature.

This is Talk Origins best argument but yet it is still flawed.
 * They are confusing climate with environment.
 * The pre Flood world had mountain, they were just smaller than many post Flood mountain.
 * Pre Flood deserts are not out of the question.
 * It is not unreasonable to think that God re-engineered some animals after the Flood to help them survive in the post Flood world.
 * There are some new discoveries in biology that suggest that there may be genetic structures and behaviors that bestow much more adaptability than previously thought.
