Lion
Individual lions rarely exceed 15 years in the wild, with males typically surviving 10-12 years due to territorial conflicts. The species itself has persisted for approximately 1.8 million years, demonstrating remarkable evolutionary staying power despite ice ages, prey extinctions, and dramatic climate shifts.
However, current population trends raise concerns about long-term species viability. With fewer than 25,000 wild individuals remaining, the lion's multi-million-year legacy faces unprecedented challenges from habitat fragmentation and human-wildlife conflict.
Procrastination
Procrastination has accompanied human consciousness since its emergence, making it approximately 300,000 years old in its current form. However, the underlying impulse to delay non-essential activity likely predates humanity itself, representing an ancient cognitive feature shared across many species.
More significantly, procrastination faces no extinction threat whatsoever. No conservation programme targets its elimination; no habitat loss reduces its range. As long as humans possess the capacity for future planning and the freedom to delay action, procrastination's survival is absolutely guaranteed.
