What is an example of how anatomical homologies are used to show evidence of common ancestry among groups of organisms?

Explanation:

In homology, origin of species occurs from a common ancestral species sharing common characters, prototype of the species are same but functionally they are different

Anatomical homologies are morphological or physiological similarities between different species of plants or animals

The species evolved through this type of homology have a common ancestor and is called cladogenesis, for example legs of horse and hands of bats, flippers of whale and hands of humans

In both the above examples, different species are involved but there is physiological similarity between them

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
