Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. Fossils, along with the comparative anatomy of present-day organisms, constitute the morphological, or anatomical, record. By comparing the anatomies of both modern and extinct species, paleontologists can infer the lineages of those species. This approach is most successful for organisms that had hard body parts, such as shells, bones or teeth. The resulting fossil record tells the story of the past and shows the evolution of form over millions of years.

Answer:
Tay-Sachs disease results from brain lacking a specific type of lipid-digesting enzyme.
Explanation:
Tay-Sachs disease occurs when relatively large amounts of gangliosides are stored in the brain. It is the oldest lipid storage disease and is a hereditary disorder caused by deficiency of a lipid-digesting enzyme known as "hexosaminidase A", which cleaves a specific bond in the gangliosides.
Its deficiency cause accumulation of gangliosides in the lysosomes of BRAIN CELLS thereby causing degeneration of the nervous system.
