Here he seems to be the further complication of the analogy. Fromconnection of units into organized groups, we turn to the breeding ofgroups and their connection in a difficult group. When Hydra reaches a knownsize, it separates from the surface of the kidney that begins to grow andgradually taking the form of a breed of her body, finally separated from him, andthis process of budding the animal inhabits the surrounding waters.The respective process is in the reproduction abovelowly tribes. When one of them will reach dimensions notcompatible with rude public form, or multiply incongruousthe number of game and other food, which can provide the surrounding country, -is seeking to clarify, and as in such communities foreverhappen to quarrels, feuds and other quarrels, soon appears to be the caseas a result of which a part of the tribe separates under the leadership of someoneof the elders and is evicted. As this process from time to timerepeats itself, then finally a vast strip of land is inhabited by numerousindividual tribes have common ancestors. The analogy is notlimited to this. Although in the ordinary Hydra offspring resulting fromthe kidneys are soon separated and made independent, but in all other respects dischargeHydrozoa, to which this animal belongs, it's not always happeningthus. Individuals, in turn evolved in this way remainattached to relatives, beget the same individuals who, inturn, remain attached to him, and the result is complexanimal. As we are in the Hydra we find the aggregation of units which, whenconsidered separately, have an affinity with the lower protozoa, so in zoophitewe see the connection of many such aggregations. The same can be seen inthe extensive family of Polyzoa or Molluscoida.
