One species may rise while others compete.

If humans vanished tomorrow, the shift would not unfold evenly. Cities would empty, infrastructure would decay, and ecosystems would begin reorganizing without warning. Some animals would disappear alongside us, dependent on what we built. Others would surge into the gaps, exploiting resources we left behind. Scientists have modeled these scenarios for years, and while no single outcome is guaranteed, certain species appear unusually well positioned to expand faster than the rest.
