Answers to Atticana

I'm on the road until the end of this month, so you probably won't see any new vids from me after this until mid-February. This video just answers several questions from Atticana (who was nominated for a Golden Crocoduck last year but is not eligible) about my video Human Ancestry Made Easy.

@utubedetective72

If your argument against speciation being the origin of ALL species is the Earth isn't old enough, perhaps you could explain these for starters:

* The existence of metamorphic rock

* Direct measurement of continental drift

* Correlation of drift with other geological data

* Direct imaging of subducted plates

* Overlapping correlation of radioisotope dating

... and no, you will not have peace here while you proclaim known falsehoods.

If only Atticana was doing satire, he'd be so funny instead of sad.

@gmsimpson05 AH, I was thinking she was farthest back we could trace, not the most recent. I get it now, DUH.

@christo930 To rephrase what this video says at 2:35, her mother would be a common matrilineal ancestor (as would her grandmother), but not the most recent one. Our most recent common matrilineal ancestor is a more recent ancestor than her mother. She was born more recently than her mother.

Let's assume you have siblings. Your mother will be your most common matrilineal ancestor with them. Your grandmother is also a matrilineal ancestor, but you have to go further back to reach her.

@gmsimpson05 Does this mean she is the most recent female ancestor that also shares her father's dna? IS there a good website that explains this? I always thought that mitochondria DNA only came down through the female.

[gmsimpson05]

*for clarity, that should have read matrilineal most recent common ancestor.

[gmsimpson05]

@christo930 Her mother is not more recent than she is. Yes, Matrilineality [matrilineal ancestry] is determined through mitochondrial DNA. This has absolutely no impact on the fact that daughters are born more recently than their mothers. Thus she is the most [matrilineal] recent common ancestor, not her mother.

[christo930]

@gmsimpson05 So does matralinia contain male DNA? I am thinking in terms of mitochondria DNA, which comes down through the female, so her mother should have the same mitochondria DNA as well. That is where I am confused.
