Question:

What is the difference between a cohort study and a case-control study

Christian O.
Answer:

In a cohort study, the investigator records the disease exposure status of each participant and then tracks the participants to see if any of them develop the disease of interest. In contrast, the investigator starts by enrolling a group of people with the disease of interest in a case-control study. The investigator also enrols a group of people without the disease and subsequently compares previous exposures between the two groups.

Question:

Is there any evidence for Darwin's Theory of Evolution?

Christian O.
Answer:

Darwinian evolution is the process by which organisms change over time as a result of changes (mutations) in traits that are subsequently passed down to their offspring. Despite still being controversial in some parts of the world, scientists have lots of evidence to demonstrate how evolution by natural selection or Darwinian evolution occurs. One of the most famous lines of evidence is the fossil record. Using fossils, researchers can reconstruct much of a species' evolutionary history. However, it is important to keep in mind that the fossil record is incomplete, leading to potentially erroneous inferences. Nowadays, scientists study the process of evolution by comparing DNA from different organisms. Using this technique, we can tell how closely different organisms are related, as well as the mutations that led to the species diverging from each other.
