Enquiry into the evolution of ageing aims to explain why survival, reproductive success, and functioning of almost all living organisms decline at old age. Leading hypotheses suggest that a combination of limited resources, and environmental causes determine an "optimal" level of repair regarding molecular and cellular level damage that accumulates over time. This process is known as self-maintenance.

  • تطور الشيخوخة أو تطور التقدم بالعمر يهدف التحقيق في تطور الشيخوخة إلى توضيح سبب انخفاض البقاء والنجاح الإنجابي وأداء جميع الكائنات الحية تقريبًا مع تقدمهم بالعمر. تشير الفرضيات الرائدة إلى أن الجمع بين الموارد المحدودة والأسباب البيئية يعين مستوى «أفضل» لإصلاح ما يتعلق بالضرر المتراكم على المستوى الجزيئي والخلوي مع مرور الوقت؛ وتُعرف هذه العملية باسم الصيانة الذاتية.
