Having trouble with the exact parsing for these, help appreciated......
43a Colonisation of earth allowed humans to be preserved (10) - SETTLEMENT (Colonisation)
I thought this looked like 'Allowed' = LET + 'Humans' = MEN, but then, assuming 'Preserved' is the containment indicator for the above, it would have to mean 'Earth' = SETT which I don't get. I've checked all the usual sources and it's either 'A badger's den' or 'Paving stone' - Where have I gone wrong?
18d Woman not one to go after morning coffee (9) - AMERICANO (Coffee)
It looks like 'Woman' = ERICA and 'Morning is AM but then the remaining NO would have to come from 'Not one to go' - I did think It could be indicating that it's 'NOT', with one (letter) 'To go', but that just seems to vague an instruction because there's no mention of T ie 'Last, to go' etc. - Help!
34d One might see prom queen arrange travel in advance (11) - CONCERTGOER (One might see prom)
