As well as the difference in quantifiability it seems to me that their
is a big difference in how relatively easy it is to collect data. If
one is studying local gravity it is quite feasible to travel to the
equator, high mountains, the poles... and measure whatever factors one
wants. Admittedly with high energy physics it is getting more and more
difficult to construct the required instruments (accelerators) to obtain
the data and in the long term this field may have to content themselves
with results that are less and less demonstratable. In order to obtain
the data that Cameron and I demand to demonstrate evolution of complex
features one has chance operating in:

a) the conditions that allow the original preservation of biological

b) the selection of exactly where to look for biological material

c) exactly how much erosion has occurred to unearth the material

In the finding of Lucy their was a lot of luck involved in looking at
exactly the right place in the Afar region. Sure clever people may
figure out the kinds of places to look in but the world is still a big
