  While quite a few recent papers have explored game-resource feedback using
the framework of evolutionary game theory, almost all the studies are confined
to using time-continuous dynamical equations. Moreover, in such literature, the
effect of ubiquitous chaos in the resulting eco-evolutionary dynamics is rather
missing. Here, we present a deterministic eco-evolutionary discrete-time
dynamics in generation-wise non-overlapping population of two types of
harvesters, one harvesting at a faster rate than the other, consuming a
self-renewing resource capable of showing chaotic dynamics. In the light of our
finding that sometimes chaos is confined exclusively to either the dynamics of
the resource or that of the consumer fractions, an interesting scenario is
realized: The resource state can keep oscillating chaotically, and hence, it
does not vanish to result in the tragedy of the commons, extinction of the
resource due to selfish indiscriminate exploitation, and yet the consumer
population, whose dynamics depends directly on the state of the resource, may
end up being composed exclusively of defectors, i.e., high harvesters. This
appears non-intuitive because it is well known that prevention of tragedy of
the commons usually requires substantial cooperation to be present.
