Explain importance of fossils as proof of evolution brainly
Answers
Answer:
Fossil fuels are the remains of the organisms which died millions of years ago. they help us to find evolutionary links of different species:
the fossils closer to the earth's surface are complex than the ones found in the bottoms that shows the evolution of species in different time periods
According to the geological time scale, humans have been evolved from the great family of apes after looking at the complete series of changing indication links between them.
hey friend, here's what you want. please mark me as brainliest
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.
Hope it helps you :)
