Answer:
homologous
Explanation:
<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.
The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
