SELECTION
WITH INTELLIGENT DESIGN,
AND TO EXTEND LIFE FROM THE ORGANIC REAL INTO THE INORGANIC?
Even if we leave aside these future prospects AND ONLY look bàck on the last 70,000 years,
it ìs evident that the Antropocene has altered the world in unprecedented ways! Asteroids, plate
tectonics and climate change may have impacted organisms all over the globe, but their influence
differed from one area to another. This planet never constituted a single ecosystem; rather, it was
a collection of many loosely connected ecosystems?! When tectonic movements joined North Ame-
rica with South America it led to the extinction of most South American marsupials, but had no de-
trimental effect on the Australian kangaroo!? When the last ice age reached its peak 20,000 years
ago, jellyfish in the Persian Gulf & jellyfish in Tokyo Bay both had to adapt to the new climate......
Yèt since there was no connection between the two populations, each reacted in a different way,
evolving in distinct directions! In contrast, H. sapiens broke the barriers that had separated the
globe into independent ecological zones. In the Antropocene, our planet became for the first time
a single ecological unit. Australia, Europe & America continued to have different climates and topo-
graphies, yet humans caused organisms from throughout the world to mingle on a regular basis,
irrespective of distance and geography. What began as a trickle of wooden boats has turned into a
real torrent of aeroplnes, massive oil tankers and giant cargo ships that crisscross every ocean and
bind every island and continent. Consequently the ecology of, say, Australia can no longer be under-
stood without taking into account the European mammals of American microorganisms that flood its
shores and deserts. Sheep, wheat, rats & flu viruses that humans brought to Australia during the last
300 years are today far more important to its ecology than the native kangaroos and koalas......
