Question

According to Hugo De Varies, speciation due to mutation is also known as 'saltation', which means

• A. single step variation
• B. variations at regular intervals
• C. single-step large mutation
• D. huge change due to natural selection

Answer 1

The correct option is C single-step large mutation

The mutation theory of evolution, given by Hugo de Vries states that new species can arise from pre-existing ones in a single generation by the sudden appearance of distinct and discrete inheritable changes or mutations in the genetic constitution of the offspring of an organism. Such single-step large mutations are known as saltations.
