Scientists today can use many investigative methods to study evolution. Which method was developed after Darwin's time?
O DNA comparisons
o observations
O comparison of fossils
O experimentation

DNA comparisons

Explanation:

The molecular nature of DNA and its role in inheritance and evolution was not known during Darwin's time.  Therefore, it was not possible to compare similarities in DNA sequences between different species to understand their evolutionary relationships.  

This type of method was not in regular use until the 1980s/1990s, when sequencing and DNA amplification technologies were invented

ans.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
