Solution
The correct option is B study of fossils
Evolution refers to the gradual changes occurring in individuals of a population that make the subsequent generations significantly different from their distant ancestors. In order to study the evolutionary mechanism, numerous pieces of evidence are gathered, namely paleontological evidence, embryological evidence, morphological and anatomical evidence.
Paleontological evidence refers to the evidence of evolution obtained from the study of fossils. For example - the proof that birds evolved from reptiles came from fossil studies on Archeopteryx.
Fossils are the preserved remains or impressions of remains of the organisms that lived in a past geological age. These could include the whole body of the extinct organism, remains of plants and animals with inorganic deposits, remains of bones or even moulds, casts and footprints on stratified rocks.
Study of the age, morphology and anatomy of these fossils, the strata (layer) of the Earth in which they were found helps scientists understand their line of descent, the period they lived in and what modern organisms they might have evolved into. Thus, palaeontological evidence plays a crucial role in evolutionary studies.
On the other hand, the study of embryonic development is known as embryology. The comparative study of the embryos of various animals provides embryological evidence of evolution.
Study of cells is called cytology. Since fossils are dead remains of plants and animals, one can not find a living cell in them.
Similarly, study of the disease in organs or tissues is a branch of medical science called pathology.
