Jeffreed << ‘I understand that such fast continental drift and plate tectonics activity at that rate would have catastrophic effects.’ you do see the humor of that statement, i hope? >>
Yeah, I see the humor. By catastrophic effects though, I didn’t mean a global flood, I meant that Noah, his family, his wooden boat, and all the 2 of each “kind” of animals on that boat, would be
crushed to smithereens.
I get this from Hugh Ross account of what would happen if you compact the 250,000,000 (million) years of plate tectonic activity into one year of a flood. There are many more problems of course…
such as pollution.
As for “how the kangaroos got to Australia.” Good question! They evolved there, and we can deduce that from the similarity of the animals of Australia to those where the continent would have fitted in 250,000,000 years ago
before the separation of "Pangea".
For a defense of the “biogeographical” argument for evolution,
see this section of Theobald’s article
SUMMARY: Common ancestors originate in a particular geographical location. Thus, the spatial and geographical distribution of species should be consistent with their predicted genealogical relationships. The standard phylogenetic tree predicts that new species must originate close to the older species from which they are derived. Closely related contemporary species should be close geographically, regardless of their habitat or specific adaptations (if not, there should be a good explanation, such as extreme mobility in the case of birds, sea animals, or human intervention).
Examples of present biogeography supporting evolutionary theory are
(1) marsupials (kangaroos, etc) which only inhabit Australia (exceptions such as some South American species and the opossum are explained by continental drift);
(2) conversely, placental mammals are virtually absent on Australia, despite the fact that many would flourish there (humans introduced most of the few placentals found on Australia);
(3) the southern reaches of South America and Africa and all of Australia share lungfishes, ostrich-like birds (ratite birds), and leptodactylid frogs – all of which occur nowhere else;
(4) alligators, some related species of giant salamander, and magnolias only occur in Eastern North America and East Asia (which were once spatially close in the Laurasian continent);
(5) indigenous Cacti (Cactus plant) only inhabit the Americas, while Saharan and Australian vegetation is very distantly related (mostly Euphorbiaceae);
(6) members of the closely related pineapple family inhabit many diverse habitats (such as rainforest, alpine, and desert areas), but only in the American tropics, not African or Asian tropics, etc.
