Houseflies have very tiny hind wings that are too small to lift them off the ground. Scientists have observed fossils of an ancient insect they believe is related to houseflies. However, these insects had second pair of wings that were much bigger.

prejudice, stereotyping, and discrimination often go hand-in-hand, but it is also possible to have one without the others. when an ethnic group is stereotyped with a neutral or positive attribute such as "family-oriented," prejudice and discrimination may not be involved.

explanation:

while prejudice refers to biased thinking, discrimination consists of actions against a group of people. discrimination can be based on age, religion, health, and other indicators; race-based laws against discrimination strive to address this set of social problems.
