Question

study of fossils is an important aspects of study of evolution

Answer 1

Fossils provide evidence in favour of evolution or establish evolutionary relationships by providing missing links. So, it is considered important in the study of evolution.

The age of the fossils can be determined by the following way:

1) Radiometric dating

In this method, the age of the fossil can be determined by tracing the radioactive elements present in the rocks and examining it chemically.

2) Relative dating

The fossils are found in the sedimentary rocks in the form of layers accumulated over the large span of time. So, using this fact, the geologist find the age of fossils in the way that the fossil found at the bottom of those layers are found to be older than that found above those.
Hope this answer helped u !

Answer 2

1. Fossils offer palaenotological evidence for the evolutionary process
2. Due to some natural calamities the organisms get buried during ancient times.
3. The impressions and remnants of such organims remain preserved underground . The hot lava also traps some organisms or their impressions. All formation form fossils.
4. Study of fossils help the researcher to understand the characteristics of the organisms that existed in the past
5. Carbon dating method also helps in finding out exact age of the fossil are obtained at specific depths
