Explanation:

1. Maurice Hugh Frederick Wilkins was a British scientist,  both a molecular biologist and physicist. He made an outstanding contribution to the scientific discovery of the DNA structure. He is well known for his work in the 1940s at King's College in London, where he used optical spectroscopy to understudy the structure of the DNA.

2. Rosalind Elsie Franklin was an expert x-ray crystallographer and chemist, she contributed immensely to the understanding and discovery of the DNA structures as well as the molecular structure of coal, RNA and viruses.

3. Linus Carl Pauling was an American scientist who made a huge impact in the field of molecular biology, he played an important role in the molecular modelling of proteins and this helped in further understanding the DNA code.

4. Erwin Chargaff was an American scientist who formulated the Chargaff's rules and his experimentations helped to show that the ratio of adenine in a DNA molecule was equivalent to the ratio of thymine, as well of the ratio of guanine in a DNA molecule was equivalent to the ratio of cytosine.

5. James Watson and Francis Crick both worked in the Cavendish Laboratory to elucidate the 3- dimensional structure of the DNA.

6. Maurice Hugh Frederick Wilkins along with James Watson and Francis Crick won the Nobel Prize for Physiology in 1962 for their discovery of the molecular structure of the DNA.

7. Rosalind Elsie Franklin was an English scientist and x-crystallographer was famous for "photo 51", this helped to first prove that the DNA was a double helix structure.

8. Rosalind Elsie Franklin worked out mathematically what a helical defraction should look like in an x-ray defraction photo.

phylogenetic tree is the tree of life or evolution tree. it shows the different branches of evolution. the sequence goes like tissues - coelom - backbone - endoskeleton - segmentation
