The Challenge of Capturing Prehistory: Paleoart vs AI
Written on
Chapter 1: The Evolution of AI in Image Generation
Reflecting on my experience with AI image generation, I recall January 29, 2022, when I first attempted to create an image of a sabertooth cat using an AI tool. The outcome was a confusing blend of browns and beiges that hardly resembled any animal. Fast forward to today, and after experimenting with DALL-E 3, I successfully generated a visually appealing image of a sabertooth. While the fangs appeared slightly off, and I noticed unexpected tiger-like stripes, the progress made in AI image generation is remarkable. (Apologies to Midjourney; despite a year of attempts, I still struggle to achieve consistent depictions of saber teeth with your tool.)
From my viewpoint as an artist and an inquisitive individual, the rapid advancement of generative AI over the past couple of years has been astonishing. We have transitioned from indistinct, dreamlike representations to high-quality images that can mimic various artistic styles, including photorealism.
Section 1.1: Understanding AI's Limitations
While the technical prowess and quality of AI-generated images continue to evolve impressively, a significant challenge remains: the datasets. These AI systems "learn" by analyzing extensive collections of images, which is typically effective for well-documented subjects. However, when it comes to iconic dinosaurs like Tyrannosaurus rex or Ice Age animals such as mammoths and sabertooth cats, a wealth of material exists. Yet, for lesser-known species, the AI struggles to produce accurate representations.
For instance, when I compared AI-generated images of three well-established prehistoric creatures—Tyrannosaurus rex, woolly mammoth, and Stegosaurus—the results, while recognizable, still exhibited noticeable imperfections. As a paleoartist, I find it fascinating yet frustrating to critique these AI outputs, as they often surpass my own illustrations without needing references. The final images, despite anatomical discrepancies, possess a vibrant quality that captures the essence of these creatures.
Section 1.2: A Closer Look at AI Image Generators
As of late 2023, DALL-E 3 demonstrates superior accuracy in depicting dinosaurs and other extinct animals compared to Midjourney. The difference can be quite striking, especially when examining images of a "triceratops." I will now delve into the challenges of generating imagery for lesser-known prehistoric species. Dinosaurs represent only a small fraction of Earth's history, and countless intriguing creatures existed long before and after them.
Attempts to illustrate creatures like Edmontosaurus, Australopithecus, and Gorgonopsid reveal the limitations of AI. For example, despite providing DALL-E 3 with specific information about Edmontosaurus being a duck-billed dinosaur, the results were still unsatisfactory. Similarly, the depictions of Gorgonopsids were wildly inaccurate, highlighting the AI's struggle with obscure subjects.
Subsection 1.2.1: Insights from Specific Examples
Some results surprised me despite the clear inaccuracies. DALL-E 3 recognized Sarcosuchus as a crocodilian without any guidance, and it generated a depiction of Opabinia in an underwater setting, albeit missing some key features. Meanwhile, attempts to portray Tiktaalik resulted in absurd representations of aquatic monsters, showcasing the AI's limitations in accurately interpreting lesser-known animals.
Chapter 2: The Art of Paleoart
When a human artist reconstructs an extinct creature, extensive research is integral to the process. As a passionate hobbyist, I can share insights into how I approach this endeavor. Artists study fossils from multiple angles, often relying on photographic references. They also integrate knowledge from living animals to make educated guesses about the appearance of the extinct species. This "fleshing out" process is crucial, and I have spent years refining my skills.
In my watercolor sketch of a Barbourofelid mother and her young, I considered recent research suggesting that the saber teeth of machairodontines were likely sheathed within the lower jaw. Additionally, I recognized that the young were born without their distinctive fangs, relying on their mother for nourishment for an extended period. For color choices, I drew inspiration from living big cats like lions and cougars, noting the evolutionary advantage of spotted coats in juvenile animals.
Section 2.1: The Intersection of Art and Science
When depicting prehistoric creatures within their environments, artists must also explore the flora and fauna that coexisted with these animals. The goal is to create illustrations that not only showcase the discoveries but also offer glimpses into ancient ecosystems. This integration of art and science results in compelling visual narratives that help the public connect with our planet's rich history.
Through skilled paleoart, artists breathe life into long-extinct species, allowing viewers to appreciate them as real beings rather than mere abstract concepts. While artistic interpretation is necessary, the endeavor remains rooted in scientific inquiry.
Conclusion: The Future of Paleoart
Despite the impressive capabilities of AI image generators, they were not designed for the nuanced task of paleoart. The technology lacks the precision required for scientific illustration and falls short when tasked with representing obscure species. AI operates effectively within general themes but struggles with the intricate details essential to paleoart.
As we navigate an era of rapid advancements in artificial intelligence, the realm of paleoart remains firmly in the hands of human creativity and expertise. This field continues to play a vital role in bringing ancient narratives to light with accuracy and depth. While we may find ourselves in an era of technological marvels, the vast and intricate world of life that once thrived remains best portrayed through the dedicated efforts of talented artists.
