Answer:
The corpus callosum is a large, C-shaped nerve fiber bundle found beneath the cerebral cortex. It stretches across the midline of the brain, connecting the left and right cerebral hemispheres. It makes up the largest collection of white matter tissue found in the brain
Answer:
A remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in the earth’s crust is called a fossil.
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
Usually only a portion of an organism is preserved as a fossil, such as body fossils (bones and exoskeletons ), trace fossils (feces and footprints), and chemofossils (biochemical signals).
Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
Paleonthological Evidences are also used for study of fossils for study the fossils as the oroof of evolution By the method of C-14 (Carbon dating method it is based upon the radioactive decay of naturally occurring C-14 and it is developed by WILLARD LIBBY )
The last paragraph is refered from the 10SSC biology book chapter no. 1 HERIDITY AND EVOLUTION for detail information of C-14 method you can refer
