The First Animal Species Extinct Due to Human Activity: The Dodo

The dodo, Raphus cucullatus, is widely recognized as the first animal species to go extinct due to human activity. It was a flightless bird endemic to the island of Mauritius, located in the Indian Ocean. The dodo became extinct in the late 17th century, around 1681, due to a combination of hunting by humans and the introduction of non-native species that preyed on dodo eggs and competed for limited food resources.

Human Impact on the Dodo's Habitat

The arrival of humans on Mauritius was a pivotal moment in the dodo's history. The island's natural balance was disrupted as humans hunted dodos for both sustenance and profit. Additionally, the introduction of invasive species such as rats, pigs, and monkeys led to a significant decline in dodo populations. These non-native predators devoured dodo eggs and competed with the birds for available food resources, effectively accelerating the species' demise.

Island Biodiversity and Theoretical Debates

While the dodo is often cited as a symbol of human-caused extinction, there is evidence to suggest that other species may have been driven to extinction even earlier due to human activity. Islands, in particular, are vulnerable to such disruptions as they often harbor unique and isolated ecosystems. However, the dodo remains the most famous and well-documented example of a species driven to extinction by human influences.

Survival Struggles and Extinction

The last dodo was likely hunted to extinction in the late 1600s. The environment on Mauritius, once rich in resources, began to change as a result of human activities. Many animals that had coexisted with the dodo were also hunted to near extinction, leaving the dodo with few options for survival.

Starvation played a significant role in the dodo's decline. As the availability of its natural prey diminished, the dodo struggled to find sufficient food. Additionally, cannibalism among the birds was reportedly observed, occurring as a result of extreme scarcity and stress. This chaotic behavior, driven by desperation, resulted in the dodo becoming an incestuous species, further compromising its survival.

Debates and Historical Context

While the extinction of the dodo is a widely accepted historical fact, there is ongoing debate about whether human activity was the sole cause or if other factors contributed. For instance, there is some controversy surrounding the extinction of the woolly mammoth. Some researchers argue that climate change and human hunting likely contributed to their demise, while others suggest that human factors alone could not have caused their extinction.

Historically, the Earth has experienced several periods of significant biodiversity loss, often linked to climatic events and mass extinction events. However, the extinction of the dodo stands out as a clear example of how human activity can lead to the rapid decline and ultimate extinction of species within a relatively short period.
