Yes a proper definition of altruism should account for its evolutionary origins. Altruism evolved via kin selection where the cost to the altruist is outweighed by the benefit to the altruist's kin via reciprocity pools as you described. Ignoring the evolutionary adaptiveness of altruism to such an extent that you are benefitting people which have ~0 potential to benefit you or your kin and are more likely to negatively effect you (e.g. via them being net fiscal burdens on you and your kin, etc.) is evolutionarily maladaptive. EAs do this for (dubious, imo) philosophical reasons but can be understood from an evolutionary lens as a costly signaling mechanism of evolutionary fitness.
