Mima mounds are low, flattened, domelike mounds composed of loose unstratified sediment as a over-thickened top soil (A Horizon). These mounds come in many sizes of mound and groups of mounds. There are three theories on how Mima mounds originated.
The first theory is that they are made by Native Americans. There have been records of similar structures being created by Native Americans during burial rites. Because of the similarities in the structure it was concluded that the Mima mounds were made by Native Americans.
A second theory is they were created by a major earthquake. Seismic activity generates vibrations through the earth that can move sediment and loose soil. This is concluded based on the loose structure of the soil in the Mima mounds.
Finally, the third theory is that they were created by pocket gophers. More commonly referred to as gophers, they are burrowing rodents of the family Geomyidae. A reason that these creatures, who live mostly underground, would create these large mounds of earth in nutrient poor landscapes would be to provide a place for them to go when it rains. This way they are above the water line and can receive plenty of oxygen.
The given passage defines Mima Mounds as low, flattened, domelike mounds compased of loose unstratified sediment as a over-thickened top soil. The speaker in the lecture completely agrees to the given definition of Mima Mounds and also confirms the validity of information present in the first paragraph of the given passage.
Speaker in the lecture is quite skeptical about the theories related to Mima Mounds. The first one says that, they are made by Native Americans and also records of similar structures being created by them during burial sites are present. Speaker casts doubt on this and says that there is no specific evidence confirming the originality of creators of Mima Mounds. Also, remains of American bodies were absent from the constituents of Mima Mound. Hence, speaker says that there's no enough information for the first theory to be valid.
The second theory specifies that they were created by major earthquake. According to the speaker, Mima Mounds are basically found in the areas with low seismic activity. Hence, second theory is also not an enough reason for Mima Mound to be formed by earthquakes.
The third theory specifies that Mima Mounds were created by pocket gophers and specifies the conditions under which they might have been created. Speaker casts doubt on the given information and says that, gophers basically live in already created Mima Mounds. They live in there opportunistically. Even experiments consisting of metal tracers buried in such Mounds were carried out, which concluded that gophers push the soil towards the centre, hence, creating Mounds like structures over large amounts of time slowly and consistently.
Hence, according to the speaker, although, the given information might be correct but still the evidence is not strong enough to prove the correct existence of Mima Mounds.
