Yes, a fish fin and a whale flipper are considered analogous structures because they have similar functions (swimming) but are derived from different evolutionary origins. Fish fins are adaptations for movement in water, while whale flippers are modified limbs evolving from a common ancestor with land-dwelling mammals.
According to evolutionary theory whlaes are descended from land animals, though these land animals probably looked quite different than whales do.

Green algae are members of the Kingdom Plantae and are thought to be the direct ancestor of land plants. This evolutionary relationship is supported by similarities in cell structure and photosynthetic pigments between green algae and land plants.
The first animals to enter land were the invertebrates, followed by some fish which later evolved into amphibians.
B. green algae is thought to be the ancestor of land plants. Molecular and fossil evidence suggests that land plants evolved from green algae approximately 500 million years ago. Both share similar traits, such as chlorophyll and cell wall composition, indicating a close evolutionary relationship.
