Answer the questions based on the figure below: Which processes does the figure demonstrate?

When new organisms join a population, changing allele frequencies is called immigration. These new organisms would bring new genes or alleles to the existing population that resulting in the transfer of alleles at the genetic level. The series of incidents in the given diagram shows that a beetle of another population is migrating to another population that will result in the transfer of alleles.

Fossils are remains, tracks, impressions, or traces of organisms that existed in the past. These are the remains or impression of prehistoric animals and plants that were embedded in the rocks.These remain also embedded in volcanic ash, sedimentary rocks, peat, amber, etc ., and get preserved and are an important tool for evolutionary studies.

Observe the diagrams and answer the questions based on them. To which animals do organs I and II belong?

Homologous organs are those organs that have the same origin but perform different functions. They have developed by divergent evolution. Example: Forelimb of humans and wing of bird have same basic structure but perform a different function. The organs I belongs to animal bat and organ II belongs to animal whale.
