Hello

the more general characters of a large group appear earlier in
the embryo than the more special characters
From the most general forms the less general are developed, and
so on, until finally the most special arises
Every embryo of a given animal form, instead of passing through
the other forms, rather becomes separated from them
Fundamentally, therefore, the embryo of a higher form never
resembles any other form, but only its embryo
