How does the fossil record support the theory of evolution?
1 point
o
it can be used to show how humans are really just apes.
doesn't support the theory, -no actual fossils or bones have been found.
o
it can be used to show how organisms have remained exactly the same over time.
o
it is physical evidence that can be used to show a change over time in organisms.

Fossil record support the theory of evolution because it provides certain physical evidences that could be used to show a change over a time period in organisms.

Explanation:

Evolution is the changes inheritable in nature which accounts for better adaptions and survival to the changing environment. For example natural selection, gene drift and so on. Fossils are the remnants of animals engraved in layers of rock that used to live on earth millions of years ago, but now became extinct, due to lacking of adaptability and evolution to survive in the changing environments. For example, the fossils of Neanderthals, the precursors of modern human, provides evidences as to how the modern human has undergone certain changes to survive in the changing environmental conditions.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
