discontinuity

Species are definitely discontinuous, and this is the only discontinuity which Nature shows us.

The idea of continuous evolution is here maintained in opposition to Comte's and Mill's philosophy of discontinuity.

In any other way, as far as I can see, there will be a discontinuity at some point on the inhabited part of the earth.

His main thesis is the absence of all essential difference and all absolute discontinuity between living and not-living matter.

But the inspection of these changes give us no right to believe that there has been any discontinuity in natural processes.
