I got handed a leaflet from a Austrailian group and on in it, it had an arguement saying that evolution violated the law of thermodynamics - could someone verify that my thinking in this statement being wrong? Cheers

1) The Earth is not an isolated system; it continually receives energy from the sun.

2)Most of the anabolic reactions in living things are driven by the hydrolysis of ATP in small steps.

3) Even though the production of ATP is catalysed by light; the fate of all energy in the ecosystem is eventually radiated back out into space as heat - heat is of thr highest entropy.

All of my ancestors arrived in Philadelphia since between 1690 and 1880. When I was 6, I was taken south. At 20 I returned and had the happiest days of my life because I felt so at home and had so much energy. I left again in 1776 for the south but I never felt really happy there. Within 8 months I got depressed and images of Philly returned..The longing for Philadlephia never went away really. Finally I moved to Europe after 16 years in the south. When I arrived I started to bleed and it did not stop. After 6 weeks of bleeding, I went to 2 doctors-one said my body was sensitive to change in lat. and longitude.The second one said the same but she was a natural medicine doctor and prescribed some little round things from her cabinet and the next morning I stopped bleeding. I like Europe better than the south, but for 30 years I still have longings for Phil. . I wonder if there is some kind of DNA or gene which develops over years in families which localizes itself to an area.
