"Dave", the feathered lizard fossil is thought of as a(n)<u> </u><u>homologous</u> species, or an organism that may represent a common ancestor shared by different but related lineages of organisms.
<h3>What is homologous evolution?</h3>
Homologous evolution is similarity of the structure, physiology, or development of different species of organisms based upon their descent from a common evolutionary ancestor.
Homologous structures include the human arm, a bird or bat's wing, a dog's leg, a dolphin or whale's flipper, and the wing of a bird or a bat. They are distinct and serve different purposes, although they are comparable and have similar characteristics. They are regarded as homologous structures because their underlying anatomies are comparable.

Answer:
The coastal upwelling and changes in wind and water circulation patterns is the main natural cause of dead zones.
Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies.
Explanation:
Coastal upwelling is the cause of dead zones in which water that is present in depth comes to the surface of ocean due to the movement of water because of wind. Fertilizers cause hypoxia due to the over growth of algae on the surface of water bodies. The fertilizers increases the algal growth by providing nutrients necessary for its growth. This over growth decreases oxygen concentration in water and affect marine organisms.
