Question

Who was the first scientist to estimate the human population
A. Darwin
B. Malthus
C. Garrod
D. Vavilor.

Answer 1

Hint: He became an 18th-century British philosopher and economist mentioned for the Malthusian growth model, an exponential method used to challenge populace increase. The theory states that meals manufacturing will now no longer be capable of preserving up with increase in the human populace, ensuing in disease, famine, war, and calamity.

Complete answer:
To answer this question, first, we need to know about the human population. Population is the wide variety of population occupying an area (which includes a country or the world) and always being changed through increases (births and immigrations) and losses (deaths and emigrations). As with any organic populace, the scale of a human populace is confined through the sources of meals, the impact of diseases, and different environmental factors. Human populations are similarly stricken by social customs governing replicas and through technological developments, in particular in remedy and public health which have reduced mortality and prolonged the existence span.
Now, let us find the solution from the option.
Darwin's greatest contribution to biological science is that he finished the Copernican Revolution through drawing out for biology the belief of nature as a system of movement ruled through natural laws. He did not estimate human populace.
Malthus in his "Essay at the precept of populace" (1798) mentioned that populace has a tendency to growth in geometric development whilst nutrients transfer rises only in arithmetical development.
Archibald Garrod became the primary to attach a human disease with Mendel's laws of inheritance. He did not estimate human populace.
Centers of diversity were first identified in 1924 through Nikolai Vavilov. So, he was not concerned with the estimation of human populace.

Hence, the correct answer is option (B)

Note: Malthusianism is the concept that populace increase is probably exponential whilst the increase of the nutrients transfer or different assets is linear. It derives from the political and financial concept of the Reverend Thomas Robert Malthus, as specified in his 1798 writings, An Essay at the Principle of Population.
