280 THE HISTORY OF CREATION. 
by the fact that the human egg is nothing more than a 
simple cell (Compare p. 124.)

In order to form an approximate conception of the organ- 
isation of those ancestors of Man which first developed out 
of the single-celled Primzeval animals, it is necessary to trace 
the changes undergone by the human egg in the beginning 
of its individual development. It is just here that ontogeny 
guides us with the greatest certainty on to the track of 
phylogeny. We have already seen that the egg of Man Gn 
the same way as that of all other Mammals), after fructifica- 
tion has taken place, falls by self-division into a mass of 
simple and equi-formal Ameeba-like cells (vol. 1. p. 190, 
Fig. 4D.) All these divided globules are at first exactly like 
one another, naked cells containing a kernel, but without 
covering ; in many animals they show movements like those 
of the Amcebe. This ontogenetic stage of development 
which we called Morula (p. 125), on account of its mulberry 
shape, is a certain proof that in the early primordial period 
there existed ancestors of man which possessed the form 
value of a mass of homogeneous, loosely connected cells. 
They may be called a community of Amabe (Synamcebee). 
(Compare p. 127.) They originated out of the single-celled 
Primeval animals of the second stage by repeated self- 
division and by the permanent union of the products of 
this division.

animals, and also in that of the lowest Vertebrate animals,
