heterogenesis

1 It points out that the replacement of traditional ideas by modern science is an important reason for heterogenesis to die out.

认为近代生物学实验科学体系取代传统哲学思辨体系，是化生说退出历史舞台的重要原因。

2 No serious observer, acquainted with modern microscopic technical methods, has been able to confirm the explanation of their observations given by the few modern believers in heterogenesis.

3 On the basis of such experiments Korschinsky developed the theory which had been proposed by Koelliker in Wuerzburg thirty years earlier, namely, the theory of "heterogeneous production" or "heterogenesis," as Korschinsky calls it.

4 From time to time there have been observers who have maintained a belief in the opposite theory, to which the name heterogenesis has been given.
