The wing of a bat and the forelimb of a dog are homologous structures. What does this mean?Group of answer choicesThey descended from a common ancestor.They have the same function.Dogs evolved from bats.They are the same organism.

The forelimbs of mammals are examples of homologous structures.

Homologous structures are anatomical features that are similar in different species because they were inherited from a common ancestor. For example, the forelimbs of humans, whales, and bats. Is a clear example of ___________________ homology, which indicates a common evolutionary origin. Question 8Answera.vestigialb.molecular c.anatomicald.embryological

Examples of homologous structures include:Question 14Select one:a.the wings of a bat and bird.b.the wings of a bat and the limbs of a cat.c.the limbs of a cat and limbs of a tortoise.d.All of the above

Early during development, organisms as diverse as a human, a mouse, and a bat can appear indistinguishable.  All of their embryos look nearly identical, suggesting thatGroup of answer choicesthis is a coincidental resemblance between them.similiar structures have developed because of convergent evolution.these very different species have a shared ancestory with all mammals.during development, humans go through stages of being a mouse and a bat.

Examples of analogous structures include:Question 2Select one:a.the wings of a bat and bird.b.the wings of a bat and the limbs of a cat.c.the limbs of a cat and limbs of a tortoise.d.all of the above.
