Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).
<h3>
What are homologous structures?</h3>
A physical trait that distinguishes two or more species, such as a complicated bone structure or a body plan, may have been passed down from a common ancestor.
A common ancestor's evolutionary history causes physical characteristics to be homologous.
Sometimes, structures in an organism are similar to crucial structures in other animals, but they no longer serve the primary ancestral role. Vestigial structures are these structures, which are frequently scaled down.
Therefore, Physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures).

Explanation:
The article, "Human Impact on the Galapagos Islands" and the video "Long Line Fishing Threatens Wildlife of the Galapagos Islands", both mentioned that fishers catch animals in the water bodies that are not their main fishing targets. Some of these animals include sea lions, sharks, sea birds, and the albatross.
In the article, it was explained that overfishing was becoming a major problem of the Galapagos Islands. Sea cucumbers and sharks were described as targets that are endangered and might soon become extinct.
In the video, sea lions, sharks, sea birds, and albatross were mentioned as targets of long line fishing which negatively affect the ecology of the Galapagos Island.
