'take something up' is the definition.
I can't judge whether this defines the answer.

'nowadays choose' is the wordplay.
'nowadays' becomes 'AD' (AD, Anno Domini, as opposed to BC, Before Christ).
'choose' becomes 'opt' (both can mean to pick something).
'ad'+'opt'='ADOPT'

'to' acts as a link.

Can you help me to learn more?

(Other definitions for adopt that I've seen before include "Formally approve" , "Choose as one's own" , "Assume (attitude)" , "Acquire" , "Take on (another's child)" .)

I've seen this clue in the Evening Standard.
