Question

In trying to understand human migration, researchers have studied mtDNA to track: A.) Changes in skin color B.) Variation in human height C.) Female lineages D.) Increases in brain size Because scientists have the complete genome of a Neanderthal, it is becoming more likely that an attempt will be made to create a living Neanderthal clone(s) in the near future. What is a likely consequence of this? A.) Neanderthals could hybridize once again with modern humans and begin the same genetic issues as happened in the past B.) Could function as a segue to cloning actual modern humans C.) All of these are likely consequences D.) Neanderthals repopulate and compete against humans Which human population was designated as having the highest levels of DNA from Archaic Human ancestors? A.) South Asians B.) Melanesians C.) Europeans D.) East Asians

00:01 Alright, so, researchers track mtdna.

00:04 So mtdna is known as mitochondrial dna.

00:15 And this essentially allows us to trace the female lineage.

00:20 Because we all have mitochondrial dna, and all of our mitochondrial dna is derived from our mothers.

00:37 So it's tracking the female lineage.

00:42 Let's see.

00:43 Alright, now because scientists have a complete genome of the neanderthal, it became more likely than an attempt to be made to create a living neanderthal clone in the near future.

00:55 What is the likely consequence of this? so we know that some portion of humans, modern humans, actually have neanderthal dna.

01:04 So it's entirely possible that neanderthals, had they exist currently, or rather in the we know that neanderthals actually mix with modern humans, or rather the ancestors of modern day humans.

01:19 So we'll just say homo sapiens, really.

01:24 Because we are derived from homo sapiens, whereas the neanderthals are homo neanderthalus.

01:31 So still humans, just a different species of human.

01:34 But current modern day human species actually have some percentage of neanderthal dna.

01:41 Okay? this means that neanderthals and homo sapiens mated, and otherwise known as hybridized.

01:53 That's essentially what that means.

01:59 So not only can neanderthals hybridize, let's see, b, could function as a segue to cloning actual modern humans...
