What is the characteristic of speciation occurring in a uniform progression over time?

  1. Punctuated equilibrium

  2. Adaptive radiation

  3. Gradualism

  4. Hybrid speciation

The correct answer is: Gradualism

Gradualism is the characteristic of speciation occurring in a uniform progression over time. This means that evolutionary changes happen slowly and steadily over a long period, without significant sudden changes. Punctuated equilibrium, on the other hand, describes rapid bursts of change followed by long periods of stability. Adaptive radiation refers to the diversification of a group of organisms into different forms to adapt to different environments. Hybrid speciation involves the mating of two different species to create a new hybrid species.
