LIFE SCIENCE

Detailed explanation-1: -The fossil record was incomplete in Darwin’s time, but many of the important gaps that existed then have been filled by subsequent paleontological research. Perhaps the most persuasive fossil evidence for evolution is the consistency of the sequence of fossils from early to recent.

Detailed explanation-2: -The fossil record is the primary factual evidence for evolution in times past, and evolution is well documented by further evidence from other scientific disciplines, including comparative anatomy, biogeography, genetics, molecular biology, and studies of viral and bacterial diseases.

Detailed explanation-3: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.

Detailed explanation-4: -Fossils document the existence of now-extinct species, showing that different organisms have lived on Earth during different periods of the planet’s history. They can also help scientists reconstruct the evolutionary histories of present-day species.

Detailed explanation-5: -Some of the types of fossil evidence commonly used by scientists include trace fossils, molds and casts, replacement fossils, petrified fossils, amber and original material fossils. A trace fossil is any indirect evidence left by an organisms.
