But this theory is too slow for the nineteenth century, and so neither Huxley, nor Parsons, nor Mivart, nor even Wallace, accepts the doctrine as Darwin propounds it.
It is, in fact, already becoming unpopular among scientific men.

Lyell proposed the origination of new species by leaps; as we see great geniuses born of commonplace parents; and Huxley supports that opinion, and Parsons, Owen and Mivart coincide in this inexplicable explanation.
The author of the Vestiges of Creation accounts for improved species from a prolongation of the period of gestation.

But Hyatt and Cope derive them from quite the contrary process--accelerated development of gestation.MM.Ferris and Kolliker derive them from parthenogenesis, a mode of genesis of which our world offers no example whatever.
