Okay, so here we have a question which we are asked to identify the techniques that, excuse me, the technique that scientists use that compares the genetic material of regional populations of humans, which helps them to identify how and where humans originated and also how and where they migrated to and from.
00:24
Okay.
00:24
So basically they take the genetics of people from france and they'll compare them to, let's say, the genetics of people from japan.
00:34
Okay.
00:35
And i won't get into it because it's a long, complicated discussion, but we're just looking for the name of that technique.
00:41
Okay.
00:42
So the first choice they give us is a word called paleo archaeology.
00:54
Okay.
00:54
So paleo archaeology, it looks like a good word.
00:58
Looks like it could be a potential answer.
01:00
Okay, so let's break this down.
01:02
So archaeology is a study of old things from the past that humans use in their cultures.
01:09
Okay.
01:10
So an archaeologist is someone think about like indiana jones.
01:15
And then paleo is a study of really deep time, right? things that happened really, really long time ago.
01:22
So this one has potential.
01:23
Maybe, but i don't think that's it.
01:26
There's nothing in here about genetics.
01:28
They aren't really geneticists.
01:30
They don't study the genetics of these people in the past.
01:33
Okay.
01:34
So we're going to say that b, a, is not the correct answer.
01:38
Okay.
01:38
So let's move on to answer choice b.
01:42
Okay.
01:42
So this one is cultural anthropology.
01:51
Now in this word, and these two words, excuse me, anthropology.
01:57
So we see the base of this word is anthro, and then you have ology.
02:02
Okay.
02:04
So we can, knowing what we know about words, and the roots of words, we can say that, okay, this is something anthro.
02:11
Anytime we see something like this, it's probably to do with apes or man or human, correct? and of course, ology is the study of.
02:19
So the study of man.
02:20
Okay, well, that's pretty good.
02:22
But then you look at the first word, cultural.
02:25
Well, we're not really looking at cultures, are we? we're looking at the genetics.
02:29
Okay.
02:30
So i'm going to take a leap here and i'm going to say, i don't think that's it either...
