Fossils are one of the best evidence of evolution, mainly because they are the remains of living organisms from the past, which allow us to compare them with living organisms. However, the fossil record is notoriously incomplete and it is also biased in favor of animals with hard body parts, such as skeletons and shells. Soft bodied organisms and soft body parts are rarely preserved and there are often huge gaps in some evolutionary sequences. For example, Archaeopteryx is the earliest known bird, but it is already a bird, nothwithstanding some of the features that are unquestionably reptilian. The earliest known reptile with feathers is Longisquama, but there is a gap of some 75 million years between Longisquama and Archaeopteryx, and nothing has yet been found that are intermediate between these two important fossils.
Finally, DNA is virtually unobtainable from fossils, making it nearly impossible to compare the DNA of most fossils with living organisms. In terms of phylogenetic tree construction, DNA data is far superior to fossil evidence. However, if not for the existence of fossils, DNA data alone would be unconvincing as evidence of evolutionary change.

The cash crops are the crops, which has more commercial values as compared to the normal crops. The cash crops are essentially grown for the purpose selling.
The Europeans forced the native Americans and Africans to grow commercial crops, which include cocoa, peanuts, coffee, sugar,cotton, palm oil, rubber, tea, timber and tobacco. Out of which, tea, cotton and tobacco were the most forced cash crops.
Hence, the correct answer is tea, cotton and tobacco.

Explanation:
The Sun's gravitational pull keeps our planet orbiting the Sun. The motion of the Moon is affected by the gravity of the Sun AND the Earth. The Moon's gravity pulls on the Earth and makes the tides rise and fall every day.
Answer:
The comparison of a measurement with a known standard, used to determine whether the measurement is reliable. Measurement accuracy is identified as the difference between the measurement of a factor and the accepted value for that factor from a trusted external source, or the percentage by which the two values differ.
