Answer 4

Answer 5

Actually it is D

Answer 6

Darwin was unaware about the genetics involved in variation. He didn't knew about DNA.

Answer 7

so also, another question, since he didn't know about DNA, D should be the correct answer?

Darwin synthesised information from several sources in developing his theory of
evolution by natural selection. Which of the following did not influence his
thinking?
a) the biogeographic distribution of species that he observed on the
Galapagos Islands
b) Lyell's Principles of Geology, which described the gradualness of geologic
changes over long periods of time
c) examples of major changes in domesticated species produced by artificial
selection
d) Mendel's paper describing the basic principles of inheritance

Answer 8

Even Mendel didn't knew about DNA. He just said that there are some factors which carry genetic information.

Answer 9

Did Darwin know anything about Mendel?
