study of fossils is important spect of stad of evolution or explain the importance of fossils. proof of evolution.
Answers
Answer:
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Answer:
i. Remnants and impressions of organisms which get buried and remain preserved underground are called fossils. Study of fossils is an important aspect of study of evolution.
ii. Carbon consumption of animals and plants stop after death and since then, only the decaying process of C-14 occurs continuously.
iii. In case of dead bodies of plants and animals, the ratio of C-14: C-12 changes continuously instead of remaining constant as C-12 is non – radioactive.
iv. The time passed since the death of the plant or animal can be calculated by measuring the radioactivity of C -14 and the ratio of C-14 to C-12 present in their body.
v. This is carbon dating method. It is used in determining the age of human fossils and manuscripts.
vi. Once the age of the fossil is determined, it becomes easy to deduce information about the erstwhile organisms.
vii. It seems that vertebrates have slowly originated from invertebrates.
