Question

Q3. Darwin was inspired by the idea of the demographer Thomas Malthus that population is limited by food supply. How is this idea a concern for human populations today? What steps might be taken to address this issue in the future?

Q4. Darwin originally did not publish his theory of evolution by means of natural selection as he was well aware of the controversy it would generate. More than 150 years later, and backed by massive amounts of evidence spanning many scientific disciplines, evolution remains a subject of controversy among the general public. Why has evolution always been the subject of fierce debate?

Answer 1

Ans 3. Malthus idea of population is that day by day population of organism increases but resources are limited. Due to this competition arise between organism which result in loss of weak species . In modern time, increement in population is increase in a very high rate due to which resources are consumed fastly. As a result this creates a drastic situation of severe competition between species.

Ans4. In ancient time, the main reason of evolution not determined that how evolution occur. What changes occur in species which turn evolution. Some scientist say it is due to different environmental condition, some say becoz of sexual reproduction and some say due to mutation. Evolution is not a process which occur by only one factor it is a result of several combinations of different factor which leads to ultimately evolution. Due to this evolution always a topic of debate.
