Question

The process of evolution
A. Is a continuous process
B. Is a discontinuous process
C. Was continuous in the beginning but discontinuous now
D. Was discontinuous in the beginning but continuous now

Answer 1

Hint: Evolution from ancestors to modern species requires time and involves intermediate forms. It takes time and is a slow, gradual process without any discontinuity.

Complete answer: Evolution is a stream in the biological studies.
1. It deals with the gradual changes occurring in the heritable characteristics of biological populations over several successive generations.
2. The process of evolution describes how modern organisms emerged from ancient ancestors. According to Charles Darwin, certain variations are better adapted to the environmental conditions of a particular time and in each generation, those adaptations gradually accumulate over a period of time.
3. These adaptations ultimately give rise to new species. Hence, the most important requirement in speciation is time.
4. The intermediate forms between ancestors and present-day modern species i.e. the “missing links” between extinct and extant species strongly support the fact that evolution is a continuous process.

Additional information: Evolutionary biologists have continued to investigate study various aspects of evolution by forming and testing hypotheses as well as forming theories based on evidence from the field or laboratory and on data generated by the methods of mathematical and theoretical biology.
Their discoveries have influenced not just the development of biology but many other scientific and industrial fields, including agriculture, medicine, and computer science, etc.

So, the correct answer is A. Is a continuous process.

Note: The scientific theory of evolution was given by Charles Darwin. According to this, natural selection plays a significant role in evolution. Natural selection also occurs gradually and slowly.
