Explanation

This fallacy occurs when Object A (with property Y) and Object B are shown to be similar in many areas, and this similarity is used to show why Object B must also have property Y. For example:

Bananas and telephones are both shaped to fit our face, so bananas must, like telephones, be designed.

This is fallacious because a similarity in one area doesn't imply a similarity in another. For example:

Bananas and telephones are both shaped to fit our face, so bananas must, like telephones, be inedible.

The argument is structured the same, but the conclusion is now more obviously incorrect.
