4 0 0 26 0 1 0 0.00000 4 31 519 29 134 1.  Increase in K is well-defined pattern over the

4 0 0 26 0 1 0 0.00000 4 31 261 29 171      last 200 million years

4 0 0 26 0 4 0 0.00000 4 31 534 29 245 2.  Catastrophe important; alters the rate of growth

4 0 0 26 0 1 0 0.00000 4 31 571 29 319 3.  Unaltered rate would have produce human level of

4 0 0 26 0 1 0 0.00000 4 31 354 29 356      EL about 60 million years ago

4 0 0 26 0 4 0 0.00000 4 31 571 29 430 4.  Oceanic rate higher 700-230 million years ago but

4 0 0 26 0 4 0 0.00000 4 31 387 29 467      then the continental rate is higher

4 0 0 26 0 1 0 0.00000 4 31 596 29 541 5.   Smooth extrapolation backwards suggests it takes 20

4 0 0 26 0 1 0 0.00000 4 31 451 29 578       billion years for intelligence to emerge

4 0 0 26 0 0 0 0.00000 4 31 568 64 669 Speculation:  Terrestrial Ecosystems impaired flow of

4 0 0 26 0 0 0 0.00000 4 31 581 64 706 nutrients to oceans --> causes "break" in the rate of K

4 0 0 26 0 0 0 0.00000 4 31 412 64 743 increase and LOWERS the overall rate
