study of fossils is an important aspect of study of evolution
Answers
Fossils are the remains of the past living organisms either animals or plants. The evolution of any species are described by the study of fossils. Also the paleo environment which means the environment that prevailed during the past , either it was hot or cold, or whether there was massive volcanic activity or massive plate tectonism can be established by the study of fossils. Let's say how it is studied. The living organisms have the habit of adaptation to any kind of environment by moulding there behaviour and changes in there life style. For an examples, the cockroaches and it family that exist today are said to be evolved from trilobites. These trilobites are said to exist around approximately 573 million years ago but if we see there evolutionary history we will find that they had changed there shape, sizes , eye patterns , number of eyes, lenses and blind species where also recorded . Do all these fossils have been recorded ,dated and established a time age of there presence and also the environment that existed during that time.
Answer:
Fossils are the remains of organisms that once existed on Earth. They represent the ancestors of plants and animals, which are alive even today. Fossils provide evidences of evolution by revealing the characteristics of the past organisms, and the changes that have occurred in these organisms to give rise to a present organism. Fossils have the same shape as that of the original animal, but their colour and texture may vary widely. The colour of a fossil depends upon the type of minerals that form it. For example, the fossil of a bone will not have some constituents of the bone in it. It has the same shape as the bone, but it is chemically more like a rock.
