Well there are two types well known to support this theory:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
I think this info can help you a lot

Answer:

There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera

Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.  

For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.  

It shows divergent evolution and supports that these organisms have evolved from a common ancestor.

Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.

For example:

  • The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
  • Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.

Cultures of a bacterial species were incubated on the shelf of a refrigerator (5 C), out on a lab bench top (22 C), on the shelf
Setler79 [48]

D) Psychrotrophs.

Explanation:

  • Psychrotrophs are those bacteria which can tolerate cold temperature and have optimum growth above 15 degree Celsius.
  • Halophiles prefer high salt concentration.
  • Mesophiles prefer temperatures with a average of 37 degree Celsius.
  • Anaerobes grow in absence of oxygen.
  • In the given experiment, none of the bacterial cultures were placed in saline or anaerobic conditions. So, the bacterial species is not an anaerobe or halophile.
  • Again the cultures did not show growth at 37 degree celsius so they are not mesophiles.
  • Maximum growth at 22 degree celsius and a little growth in refrigerator make it obvious that the species is a Psychrotroph.
