I thought it went really well!

Did anyone else call the fossil from 1.6mya 'Turkana Boy'? I called him that throughout my answer because it's what the CGP revision guide says but I noticed the CGP revision guide had made a mistake with Pavlov's dogs

i couldnt think of many advantages other than the pest are killed so the crop yield increases.Also you can selectively breed the plants created with the toxin to increase yield . The disadvantages i said were cross breeding releasing the gene in weeds, resistance and lower biodiversity.

How many marks do you guys think this will be? And what else did you guys get?

Anyone have predictions for grade boundaries?
I predict it may be around:
A* - 52
A - 45
B - 39
C - 33
