Apes are our closest living relatives in the animal kingdom, and understanding how they age is important for both researchers and caretakers. Apes, which include species like gorillas, chimpanzees, orangutans, and bonobos, share many similarities with humans, such as advanced cognitive abilities and complex social structures. However, their aging process differs significantly from ours.
Whether you’re a wildlife enthusiast, a zookeeper, or a researcher studying the behavior of apes, knowing how to convert their years into human-equivalent years can provide valuable insights into their health, behavior, and life stages.
Why People Convert Ape Years
Many people are curious about how apes age in relation to humans. Understanding their age in human years helps us interpret the stages of their life, from infancy to seniority. For example, a young chimpanzee’s age may be equivalent to that of a young adult human, while a senior gorilla may have a human equivalent age of an elderly person. Converting ape years to human years also plays a critical role in medical care and treatment decisions for captive apes.
Popular Myths
There are several myths surrounding the aging process of apes. One of the most common misconceptions is that apes age in the same way as humans. In reality, apes experience rapid growth and development in their early years, but their aging slows considerably after reaching adulthood. Another myth is that each year of an ape’s life is equivalent to seven years in human terms, a simplification that doesn’t accurately reflect the biological aging of different species.
What is an Ape?
An ape is any member of the family Hominidae, which includes gorillas, chimpanzees, bonobos, and orangutans. These animals are primates, just like humans, and are known for their intelligence, ability to use tools, and complex social behaviors. They are typically larger and more robust than monkeys and lack tails.
How Ape Aging Differs from Human Aging
Ape aging is different from human aging in several ways. While humans tend to grow at a fairly consistent rate throughout childhood, apes experience a much faster rate of growth in the early years. For example, a 1-year-old chimpanzee may have the physical maturity of a 15-year-old human, whereas a 2-year-old ape might be equivalent to a human in their mid-20s. However, as apes get older, the aging process slows, and their later years resemble the aging process seen in elderly humans.
Understanding the Ape-to-Human Age Conversion Formula
When calculating an ape’s age in human years, it’s important to consider that the first two years of an ape’s life are much more accelerated than the subsequent years. Therefore, a simple 1:1 comparison between ape years and human years isn’t accurate.
The most commonly accepted formula for converting ape years to human years is as follows:
- The first two years of an ape’s life = 12 human years.
- Each subsequent year = 3 human years.
This formula takes into account the rapid development that occurs in the early years of an ape’s life, especially in their infancy and adolescence.
Ape Age Conversion Chart
Here’s a handy chart for reference:
| Ape Age (Years) | Human Age Equivalent |
|---|---|
| 1 year | 6 human years |
| 2 years | 12 human years |
| 3 years | 15 human years |
| 4 years | 18 human years |
| 5 years | 21 human years |
| 10 years | 30 human years |
| 15 years | 45 human years |
| 20 years | 60 human years |
This chart helps provide a visual reference of how ape aging compares to human aging across different stages of life.
How to Determine Your Ape’s Age in Human Years
Converting your ape’s age into human years is easy once you understand the formula. Follow these simple steps:
- Add 6 years for the first year of life.
- Add 6 years for the second year.
- For every subsequent year after the first two, add 3 years for each ape year.
This simple formula will give you an accurate human age equivalent based on the ape’s actual age.
Life Stages of Apes
Just like humans, apes go through various stages in their life. Here’s a breakdown of how these stages correspond to human years:
- Infant/Young (0-2 years): During this stage, apes are growing rapidly, similar to human infants. In human terms, this is equivalent to the early childhood years (0-12 years).
- Adolescent (2-6 years): This is when apes start to reach maturity, and their growth slows down. Human equivalent: early to mid-teens (12-24 years).
- Adult (6-20 years): Apes in this stage are fully mature and active members of their group. The human equivalent: young adulthood to middle age (24-60 years).
- Senior (20+ years): Senior apes experience the effects of aging, including slower movement and diminished physical capabilities. The human equivalent: elderly (60+ years).
How Many Ape Years Are in a Human Year?
The question of how many ape years equal one human year can be confusing. Unlike pets, where one dog year is roughly equivalent to seven human years, the conversion between ape years and human years follows the formula mentioned earlier. For example, a 1-year-old chimpanzee is about 6 human years old, while a 10-year-old gorilla is approximately 30 human years old.

How Do Apes Age in Human Years?
As apes age, their physical and emotional changes mirror those of humans in many ways, although at different rates. Here’s a detailed breakdown of how apes age compared to humans:
- Infant Years (0-2): Apes grow quickly in their first two years, similar to human infants. They learn basic skills, develop motor functions, and begin socializing.
- Adolescent Years (2-6): Apes go through a growth spurt and start to experience puberty. During this time, they form strong bonds with other group members, and their social skills develop.
- Adult Years (6-20): Apes in this stage are fully grown and are highly active. They begin to play important roles in their social groups, whether in the wild or in captivity.
- Senior Years (20+): Older apes start to slow down physically. They may experience age-related conditions, like arthritis or diminished cognitive function, similar to humans.
Why is It Important to Know an Ape’s Age in Human Years?
Knowing your ape’s age in human years is crucial for providing the best care possible. By understanding where they are in their life cycle, you can make informed decisions about diet, medical care, and socialization.
For example, a young adult ape may need more stimulation and social interaction, while an older ape may benefit from a quieter, more comfortable environment. Understanding their age in human years allows caregivers to better assess their physical, emotional, and social needs.
What is the Average Ape’s Life Expectancy?
The life expectancy of apes varies depending on the species. In general:
- Gorillas can live up to 35-40 years in captivity, but their lifespan in the wild is shorter due to predation and disease.
- Chimpanzees can live up to 60 years in captivity, while in the wild, they typically live around 40 years.
- Orangutans have a lifespan of about 30-40 years in the wild but can live up to 50 years in captivity.
Factors like diet, environment, and medical care greatly influence the longevity of an ape.
How Can I Tell an Ape’s Age?
While it can be challenging to determine an ape’s exact age, there are signs that can give you a clue:
- Teeth: Younger apes have sharp, fully developed teeth, while older apes may have worn-down or missing teeth.
- Eyes: Senior apes often have cloudier eyes, while younger apes have bright and clear eyes.
- Coat: Apes in their senior years may show signs of graying fur or thinning hair, whereas younger apes generally have a fuller and shinier coat.
Factors That Influence an Ape’s Aging Process
Several factors can influence how an ape ages, including:
- Diet and Nutrition: A balanced diet plays a key role in maintaining an ape’s health and longevity.
- Social Environment: Apes that live in social groups with lots of interaction tend to have better emotional and physical health.
- Genetics: Like humans, some ape species may age differently based on their genetic makeup.
- Veterinary Care: Regular check-ups and prompt treatment of illness can increase an ape’s life expectancy.
Common Myths About Ape Aging
There are several misconceptions about how apes age:
- Myth 1: “Apes age the same way humans do.”
Reality: Apes age faster in their early years and then slow down. Their aging process is different from ours. - Myth 2: “Each year in an ape’s life equals seven human years.”
Reality: This oversimplified formula does not accurately reflect the biological differences between apes and humans.
