An important evidence in favour of organic evolution is the occurrence of:
- homologous and vestigial organs
- analogous and vestigial organs
- homologous organs only
- homologous and analogous organs
The Correct Option is A
Solution and Explanation
Homologous organs show structural similarities due to shared ancestry, even if they may have different functions in different organisms. Vestigial organs are structures that have lost their original function over evolutionary time. The presence of both homologous and vestigial organs supports the idea of common ancestry and evolutionary change.
So, the correct option is (A): homologous and vestigial organs

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
