Sudan changes to deep orange or red in the presence of lipids. Sudan in not soluble in water lipids will absorb sudan's particle that will cause the change in color. Lipids will form distinct fat layer in the solution. This can be done during experiment where a macromolecule is unknown. Application of this experiment applies in health such as during confirmation of excessive fat in stool. The affinity of this dye to the lipids is high and alcoholic solutions of sudan dye can also be used.

Charles Darwin spent almost 5 years in the voyage name HMS Beagle. This voyage made him famous as after returning, he formulated the "Theory of natural selection" as he was amazed by the geographical distribution of the wildlife and also collected fossils that helped him to formulate his theory.
Explanation:
Charles Darwin was the main contributor to the theory of evolution. Besides, he was a geologist, naturalist, and biologist. He first demonstrated the branching pattern of evolution on the basis of natural selection. 18 February 1809 was his birth date and he died in 1882. He explained the theory of natural selection with the help of finches residing in the Galapagos island. The change in the beak structure of the finches according to the availability of food illustrates the process of natural selection and hence the process of evolution.
