116 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



crests above the surface, but in rough weather they sink 

 and one of their streamers entangled in a tow net might 

 do serious harm, as happens on the slime banks of Behr- 

 ing Sea, where the cod fishermen suffer grievously when 

 their lines come up smeared with a poisonous jelly fish 

 excretion. It was the 'Albatross' that traced the cause of 

 this Behring Sea fishing trouble to a jelly fish." 



We see that this colony of cells can sink when necessary 

 to evade the crushing force of the waves and again float 

 when the weather and conditions are favorable. This ani- 

 mal looks like the ordinary sea weed floating on the water 

 but upon a closer investigation we find that this is more 

 than a mere social gathering of the cells. Here they have 

 discovered the advantage of specialization ; each bunch of 

 cells takes charge of its particular line of work, such as 

 moving about, reproduction, capturing and devouring 

 smaller individuals for food. You notice that they have 

 also discovered a method by which they kill and capture 

 other animals for food by a powerful sting. It is not 

 likely that they can see or hear in the sense that we under- 

 stand that power. They can, however, feel, smell and 

 taste. The thinking capacity of the cells that make up 

 this social community must be the best, when we consider 

 the discoveries and inventions they have perfected in the 

 course of their development from the single cell to the 

 present state. Consider the million of individuals in- 

 volved and occupied with their different kinds of work, 

 in the make up of this social community. This colony of 

 cells we call Physalia or Portuguese man-of-war is called 

 an individual. 



We might next consider the Star Fish. It has one eye ; 

 and has feet with sucker ends so that it is able to walk 

 almost anywhere and in any direction. It has developed 

 a very good smelling apparatus and is very well equipped
