The ancient remains of several human bodies have been discovered and legally need to be returned to the tribe that contains the closest descendents. you have been called as a witness in the resulting legal case to give your opinion. the jury is confused about the analysis you have done. could you please explain it to them again?

Thank you for giving me the opportunity to speak to you today. I am an expert in ancient DNA analysis, and I have been working on the case of the human remains that were found in a construction site last year. These remains are very important for understanding the history and ancestry of the indigenous people who lived in this area before the arrival of Europeans.
As you may know, the law requires that any human remains that are older than 100 years and belong to a Native American tribe must be returned to that tribe for proper burial and respect. However, in order to do that, we need to identify which tribe these remains belong to. That is where my analysis comes in.
I used a technique called genotyping, which allows me to compare the DNA of the remains with the DNA of living people who have known tribal affiliations. By doing this, I can find out how closely related the remains are to different tribes, and which tribe has the highest probability of being their descendants.
In this case, I analyzed the DNA of 12 human remains that were found in the site, and I compared them with the DNA of 20 different tribes that have historical or geographical ties to this area. I used a statistical method called Bayesian inference, which calculates the probability of different hypotheses based on the available data and prior knowledge.
The results of my analysis showed that the most likely tribe that these remains belong to is the X tribe, with a probability of 95%. This means that there is a very high chance that these remains are the ancestors of the X tribe, and that they should be returned to them according to the law. The second most likely tribe is the Y tribe, with a probability of 3%, and the rest of the tribes have probabilities below 1%.
I hope this explanation helps you understand how I reached my conclusion and why it is important to respect the wishes of the X tribe and their cultural heritage. Thank you for your attention.
