The giraffe model is a theoretical model widely used in biology and ecology to analyze the relationship between animal characteristics and their living environment. At the heart of this model is the evolution of this unique species, by looking at its physiological features, especially its long neck, and correlation analysis with other factors in the ecosystem to reveal its adaptability in a particular environment.

The giraffe's neck is its most distinctive feature and is often considered one of the adaptations it has developed over the course of its evolution. By explaining the evolution of this feature, scientists have proposed a variety of hypotheses. One of the more widely accepted ideas is that the giraffe's long neck allows it to access young leaves from taller trees, providing it with an abundant food source. In ecological competition, giraffes are able to escape direct competition from terrestrial herbivores, thus occupying a unique ecological niche. In addition, the length of the neck may also play a role in attracting members of the same species during mating, further complicating the trait.

The giraffe model is not only limited to morphological characteristics, but also involves many factors such as population dynamics, environmental changes and diversity. With environmental changes, such as climate change and changes in vegetation distribution, giraffe food resources can also be affected. This leaves giraffes needing to constantly adapt their foraging behavior to new ecological conditions. Using the giraffe model, researchers can analyze population trends in response to environmental fluctuations, and thus better understand the adaptation of species.
