Much stress has been laid by some authors on the supposed fact, that →mongrel animals alone are born closely like one of their parents; but →it can be shown that this does sometimes occur with

I entirely agree with Dr. Prosper Lucas, who, after arranging an enormous body of facts with respect to animals, comes to the conclusion, that the laws of resemblance of the child to its parents are the same, whether the two parents differ

Independently of

Laying aside

the question of fertility and sterility, in all other respects there seems to be a general and close similarity in the offspring of crossed species, and of crossed varieties. If we look at species as having been specially created, and at varieties as having been produced by secondary laws, this similarity would be an
