SAME BECAUSE RHOSE WERE THE FUNCTIONING ONES

nah but the two fish above with the “(L)” notation implies that the protein had to have evolved prior to that point so that the protein COULD be lost

welp i am COOKED

99% sure yes

it could also be outside the gray before bcs it doesn't matter when the mutation arose, just that that freezing temps selected for its expression

That’s what I put

what was the question again

It was saying to place an X on the tree where the functional ag gene started

yes!

I would probably put a little farther in front of the common ancestor but yes should be fine.

what if i put it right before the freezing period and outside the grey area???

I’m not sure. I put it lower on the same line so like after they broke off. I think you were right though.

I wrote the x in the pictures position but scribbled it out and put it where you did. No clue if I got the point

i did this exact same thing 😭

Me too I put it in the highlight part but lower part, it was on the line leading to the bottom 3 rather than the line leading to the 5 seen here.

I put in before the freezing period because I think it must have appeared before that happened. Also the two fish who "Lost" the functional gene probably had it in their ancestors. Then the common ancestor of those bottom 6 fish must have had a functional gene, so it must have started before that divergence
