Language certainly constitutes an important asset for survival, but less so for the individual than for the group. Language is above all a shared attribute of a group of individuals, and in this regard, it favours the selection of groups and not of particular persons. This is the case for any animal community that has an effective means of communication. For example, like humans, bees and ants can react as a group to an outside event, thus becoming the subject of evolution by selection of groups rather than selection of individuals.
