FYI, in 2.43v, this feature iterates recursivly through all extant descendants of the selected bot, changing their species as well.
In addition, it changes all bots (be they descendants or not) with a subspecies distance of 0 or 1 from the selected bot.
Note that it is still possible some extant descendants of the seleted bot will be missed. This will happen in the case where both of the following are true
1) The chain of descent to a descendent runs thorugh a bot that is no longer living at the time Make New Species is executed. The current data structures do not currently preserve descendency information between extant bots if that descendency runs through 1 or more dead individuals.
2) That descendent has a subspecies distance greater than 1 from the selected bot, meaning that two or more mutations (or virus infections) have occurred in the line of descent between this bot and the selected bot.
