Similar structures that are modified to work in different ways in different organisms are referred to as
Answer Details
Structures that are similar in form and origin but have been **modified** over time to function differently in various organisms are known as **homologous structures**. These structures indicate a common evolutionary ancestor. For example, the forelimbs of humans, bats, whales, and cats have the same basic bone structure but have adapted differently for tasks such as grabbing, flying, swimming, and walking. Each of these organisms developed modifications in their limb structure to suit their environment and lifestyle, which showcases the concept of homologous structures. Unlike **analogous structures** that have similar functions in different organisms but different evolutionary origins, homologous structures emphasize a common ancestry with different functional outcomes.
