Understanding Homology and Analogy

What is the difference between homology and analogy?

Some traits common between 2 individuals are inherited by a common ancestor, while others share traits through convergent evolution, a process where two or more different populations evolve a similar feature/characteristic separately from one another.

Homology:

Traits, characteristics, or features inherited by a common ancestor.

Examples:

~ Twins

~ Tetrapod limbs in humans, birds, whales, and lizards.

``````````````````````````````````````````````````````````````````
Analogy:

Similarity caused by convergent evolution, not by inheritance or common ancestry. Similarities between two distinct organisms caused by environmental changes.


Examples:

~ Barnicles and Limpets (***Remember: Just because 2 organisms appear similar on the outside, does not mean that they are similar on the inside...)

~two elvis impersonators.

Marsupials Vs. Placentals

Marsupials: A mammal, such as a kangaroo, who cares for and protects their children within a maternal pouch.

Placentals: A mammal, including a human and elephant, whose young completes its embryonic development inside of the uterus. The embryo within the uterus is connected to the mother through a placenta.
