Some Animals Live Longer Than Humans

The question of why some animals live longer than humans encompasses various theological, biological, and philosophical considerations. From a biblical perspective, the longevity of different species is part of God’s sovereign design and reflects His wisdom and purpose in creation. This essay will explore the topic of animal longevity from a biblical standpoint, examining key references from the New King James Version (NKJV) of the Bible, and considering theological implications and biological factors.

Example

Some rare animals live longer than humans because of their ability to reproduce new cells to replace the old ones. An example of that is immortal jellyfish. This water creature ages in reverse, changing from an adult medusa back into a polyp. During this transformation, certain genes are converted to particular skin or nerve cells, causing them to morph back into stem cells. This special process, known as transdifferentiation, reinstates the animal’s capability to make new cell types as it restarts its life cycle, again and again.

While scientist can’t explain why this takes place in nature, for the believer, this example in the life of the jellyfish is an excellent reminder of the perfect life that God had originally created before sin and how sin ruined it. The believer is also reminded that when man disobeyed God’s command (Genesis 2:17), sin brought death into the world and man passed from the status of conditional immortality to that of unconditional mortality.

Thus, the life of the immortal jellyfish has a message of hope to the believer that if he remains faithful to God, he will have eternal life.  David wrote,  “How many are your works, LORD! In wisdom you made them all; the earth is full of your creatures.  There is the sea, vast and spacious, teeming with creatures beyond number— living things both large and small” (Psalm 104:24,25). 

God’s Sovereign Design in Creation

The Bible affirms that God is the Creator of all living creatures and has ordained their existence according to His divine will. Psalm 104:24 declares, “O Lord, how manifold are Your works! In wisdom You have made them all. The earth is full of Your possessions.” (NKJV) This verse acknowledges God’s wisdom and creativity in designing the vast array of life forms on Earth, each with its own unique characteristics and lifespan. Nature is our second book that reveals spiritual truths about God and His dealings with man. Job wrote, “ask the animal, and they will teach you” (Job 12:7).

Biological Factors Influencing Lifespan

While the Bible provides insights into God’s sovereign design in creation, it also acknowledges the role of biological factors in determining lifespan. These factors include genetic predispositions, environmental conditions, and physiological processes inherent to each species.

1. Genetic Predispositions

Genetic factors play a significant role in determining the lifespan of different species. Each species possesses its own genetic makeup, which influences various aspects of its biology, including growth rate, reproductive capacity, and susceptibility to disease. Some species are genetically predisposed to live longer due to evolutionary adaptations that promote survival and reproductive success.

2. Environmental Conditions

Environmental factors such as habitat, climate, food availability, and predation also impact the lifespan of animals. Species that inhabit stable and favorable environments may experience lower mortality rates and longer lifespans compared to those living in harsh or unpredictable conditions. Environmental stressors such as pollution, habitat destruction, and climate change can also affect the health and longevity of animal populations.

3. Physiological Processes

The physiological processes governing aging and longevity vary among different species and are subject to genetic regulation and environmental influences. Biological mechanisms such as cellular repair, oxidative stress, and telomere shortening contribute to aging and senescence in organisms. Some species possess unique physiological adaptations that enable them to resist aging and extend their lifespan, while others may be more susceptible to age-related diseases and degeneration.

Biblical Perspectives on Lifespan

The Bible provides insights into the longevity of certain animals and their significance within the context of God’s creation and providence. While humans are often regarded as the pinnacle of God’s creation, other creatures also play important roles in the natural order established by God.

The Bible acknowledges the diversity of lifespans among different creatures and highlights their respective roles in God’s creation. Psalm 90:10 reflects on the brevity of human life compared to other creatures: “The days of our lives are seventy years; and if by reason of strength they are eighty years, yet their boast is only labor and sorrow; for it is soon cut off, and we fly away.” (NKJV) This verse contrasts the relatively short lifespan of humans with the enduring existence of certain animals, emphasizing the transient nature of human life in light of eternity.

Divine Purpose and Providence

Ultimately, the longevity of different species is part of God’s sovereign plan and providential care for His creation. God’s wisdom and purpose extend beyond human understanding, encompassing the intricate details of the natural world and the diverse forms of life He has created. Romans 11:33 affirms the depth of God’s wisdom and knowledge: “Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out!” (NKJV)

The good news is that at the second coming of Christ, the believer who accepted God’s offer of salvation through Christ (John 3:16; Romans 2:7; 2 Corinthians 5:4) will be given an immortal body (1 Corinthians 15:52:53). What a day that will be!

Conclusion

In conclusion, the question of why some animals live longer than humans involves a complex interplay of biological, ecological, and theological factors. While the Bible affirms God’s sovereign design in creation and acknowledges the diversity of lifespans among different creatures, it also emphasizes the limitations of human understanding and the mystery of God’s providential care for His creation. Ultimately, the longevity of different species reflects the wisdom and purpose of God, who sustains all living things according to His divine will. As believers, we are called to stewardship and reverence for God’s creation, recognizing the value and significance of every living creature in the tapestry of life ordained by the Creator.
