Question

define Fossil explain important of fossils as per of evolution

Answer 1

 Fossils are remains or traces of past organisms that have been preserved by nature. And here's a fun fact: the word 'fossil' is Latin and actually means 'obtained by digging,' which makes sense because they are often buried.......if u liked it please mark brainliest

Answer 2

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.
