Anatomy and embryology gives information on evolution. Anatomy deals with the study of the body structure of the living organisms including the humans. The study of embryos also gives information on evolution. For instance the things that will be present in a fully grown animal can be seen by monitoring the maturation of an embryo. The similarities in early stages disappear on development. For example, the human embryos have a tail like structure at a certain stage of development and gills at one of the stages. The two pair of slits of the gills disappears with the growth of embryo and final pair becomes ear and eustacian canal. This is evidence that humans had tails long ago and also had gills indicating that in the past we were aquatic or marine species.
Embryology gives an idea on how an organism looked at earlier stages. This study supports evolution. The developmental stages of several organisms when studied was found that they are very similar indicating they have evolved from a common ancestor. The anatomy of homologous features in organisms show common ancestry and thus supports evolution.

Host-pathogen interactions, emphasizing issues such as the host immune response upon infection, and the mechanism of pathogen transmission in the investigation and analysis of the different stages of infection.
<h3>Pathogen </h3>
The severity of the disease symptoms is referred to as virulence, and a pathogen is an organism that causes disease in its host. Pathogens are diverse in terms of taxonomy and include bacteria, viruses, and both single- and multicellular eukaryotes. Pathogens impact all living things, including bacteria, which are the target of specialist viruses called phages.
There are countless bacteria and viruses on the planet, and they live in virtually every environment. Over ten billion bacteria and one hundred billion viruses are generally present in one liter of surface seawater.
