Question

The given diagram shows an undisturbed sedimentary strata at the bottom of the ocean. The fossils found in layer 'B' resemble the fossils found in layer 'A'. This similarity suggests that <img class="img-fluid question-image" alt="Question" src="https://cdn.tardigrade.in/q/nta/b-49ebo863lkhx.png" /> (A) the fossils in layer 'B' were formed before fossils in layer 'A' (B) modern forms of the life may have evolved from earlier forms of life (C) vertebrate fossils are only found in sediments (D) the fossils in layer 'A' must be more complex than layer 'B'

Tardigrade Admin · Accepted Answer

Preserved remains or impressions of once living organisms from the past on Earth's crust are called fossils. Cross-section of earth's crust will provide information on the arrangement of sediments formed by rock, one over the other during the geological period. Different-aged rock sediments contain fossils of different life-forms. In the given diagram, fossil of layer B followed the fossil of layer A. It also suggests that they belong to the same region of different timeline and display similarity. From the similarity between the fossils of layer A and B, it can be deduced that modern life forms have evolved from earlier life form.

Q. The given diagram shows an undisturbed sedimentary strata at the bottom of the ocean. The fossils found in layer 'B' resemble the fossils found in layer 'A'. This similarity suggests that

the fossils in layer 'B' were formed before fossils in layer 'A'

modern forms of the life may have evolved from earlier forms of life

vertebrate fossils are only found in sediments

the fossils in layer 'A' must be more complex than layer 'B'
