Please can I get at least 20 difference between homology and analogy
Answers
Answer:
In comparing and contrasting certain traits in organisms, biologists often look at similarities in structure, function, and evolutionary ancestry. Features of animals that have similar structure are classified as homologous if they have a common evolutionary origin, even if they have different functions in different animals. A classic example of homologous structures is that of the wing of a bat and the arm of a human. Both have similar internal bone structure, and as mammals, the evolutionary origin is clearly similar. However, the wing of a bat is utilized for flying, whereas the arm of a person is used to carry items or to perform other tasks and is not suited for flight. Similarly, the leg of a dog, wing of a bird, and fin of a whale are also homologous to the human arm. Such structures are said to have diverged over time, indicating that at one time, they may have had the same function in the common ancestral organism.
