3 AMONG THE GREEKS. 



( animals from this primordial earth slime This 

 IS the prototype of Oken's Ur-Schleim 



Xenophakes (576-480) was the founder of the 

 Eleatic school, and is believed to have been a pupil 

 of Anaximander. He agreed with his master so 

 ar as to trace the origin of man back to the transi- 

 lon penod between the fluid or water and solid or 

 land stages of the development of the earth, but we 

 do not know how far he elaborated his ideas The 

 ultmiate origin of life he traced to spontaneous 

 generation, believing that the sun in warmino- the 

 earth produces both animals and plants. He is 

 famous m the annals of science as being the^^fi^^t 

 to recognize fossils as remains of animals formerly 

 alive, and to see in them the proofs that the seas 

 formerly covered the earth, and that water was the 

 element from which the earth emerged. P.rmen 

 IDES, h,s pupil, developed his cosmogony, and also 

 denved men from the primitive earth slime directlv 

 engendered by the sun's heat. 



The Physicists. 



_ The Physicists, Heraclitus, Empedocles, Democ- 

 ntus, and Anaxagoras, were far bolder and more 

 fruitful in their suggestions. Among them we find 

 that the vague notions of metamorphosis and the ' 

 I notions of Abiogenesis derived from the lonians -■' 

 were developed into surprising anticipations of the 

 true Evolution idea.
