Response Article
This article (Pre-Flood animals lived in a uniform climate (Talk.Origins)) is a response to a rebuttal of a creationist claim published by Talk.Origins Archive under the title Index to Creationist Claims.


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 quotes in blue)

1. Geological isolation allows diversity, and the lack of it causes species to go extinct. Different regions with the same climate often have very different species (for example, polar bears in the Arctic and penguins in the Antarctic). One of the leading causes of extinction today (perhaps the leading cause) is introduced species. If even one species such as a goat, pig, or snake gets into a region where it did not used to live, it can cause extinctions -- either by out-competing the indigenous species for resources or by preying on the indigenous species directly.
  • The brown tree snake has caused the extinction of many native Pacific Island birds, including nine of the eleven native species on Guam.
  • A single introduced land snail species eliminated all the native snails of Tahiti.

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.

If all the species (or even "kinds") today were kept together, most of them would quickly go extinct.

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.
2. Uniform climates do not support a wide variety of species. You find different communities in tundra, temperate forest, tropical forest, and desert because of their different climates. A single climate would rule out the biota from all other climates.

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.

3. Whatever the climate was like, some species could not survive in it. Grylloblattids thrive in cold temperatures, and many species die in temperatures above 10 degrees C (Lloyd n.d.). Temperatures that low would kill tree sloths. Some cave species require 100 percent humidity. Other species would die from fungal and algal infections at humidities even close to that high.

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.

4. All animals coming from a uniform climate strongly argues against creation. Creationism argues that features of animals are designed; for example, that the camel's desert adaptations are designed for the desert, that the mountain goat's sure-footedness is designed for mountains. (Evolution says much the same, but "designed" by natural selection.) If all animals come from the same sort of climate, there is no need for such features, so it does not make sense that they are designed.

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.
