Have you ever wondered what our ancient ancestors looked like? Scientists have reconstructed the face of an ancient ape species called Pierolapithecus catalaunicus, giving us new insight into the evolutionary history of humans and great apes.

Kelsey Pugh, a research associate in the Department of Anthropology at the American Museum of Natural History and a professor at Brooklyn College, led this fascinating study. Pugh and her team pieced together the skull of this magnificent species that lived on Earth about 12 million years ago.

Searching for Pierolapithecus catalaunicus

Discovered in northeastern Spain and first described in 2004, Pierolapithecus catalaunicus belonged to an extinct group of apes that lived in Europe between 15 and 7 million years ago. This was a time when primates were diversifying and evolving into new species, each with unique characteristics.

One of the peculiarities of Pierolapithecus catalaunicus is the condition of the fossils. The researchers have both a skull and a partial skeleton of an individual, a rare treasure in the world of paleontology. Such complex evidence allows scientists to examine more carefully how this species fits into the evolutionary puzzle.

The importance of Pierolapithecus catalaunicus goes beyond its well-preserved bones. It plays a key role in understanding the “mosaic nature of hominid evolution.” Since hominids include both apes and humans, studying this ancient ape helps scientists trace the evolutionary steps that led to modern species like us.

“The features of the skull and teeth are extremely important in explaining the evolutionary relationships of fossil species,” Pugh says. “When we find this material together with the bones in the rest of the skeleton, we can determine the species’ place on the hominid family tree.

“When we find this material together with the bones in the rest of the skeleton, it not only gives us a sense of where the species is in the hominid lineage, but it also allows us to learn more about the biology of the animal and how it moved through its environment,” Pugh explained.

Pierolapithecus catalaunicus: Upright monkey

Previous studies suggest that Pierolapithecus had an upright body structure that predated an adaptation that allowed hominids to move along tree branches, but its exact place in evolutionary history is still debatable.

“One of the persistent problems in studying the evolution of great apes and humans is that the fossil record is fragmentary, with many specimens poorly preserved and distorted,” says study co-author Ashley Hammond.

“This makes it difficult to reach consensus on the evolutionary relationships of key fossil apes, which is important for understanding ape-human evolution.”

Modern technologies at work

To solve this problem, the researchers used computerized tomography to reconstruct the skull of Pierolapithecus catalaunicus. This allowed them to compare it to other primate species and model how key features of the ape’s facial structure evolved over time. The study showed that Pierolapithecus shared facial features with both fossil and modern great apes, and also had distinctive features not found in other apes of the Middle Miocene.

These findings suggest that Pierolapithecus catalaunicus may be one of the earliest members of the ape-human family.

“An interesting result of the evolutionary modeling in this study is that the Pierolapithecus skull is closer in shape and size to the ancestor from which great apes and humans descended,” said Sergio Almécija, co-author of the study.

On the other hand, gibbons and siamangas (‘little monkeys’) appear to be secondary derivatives associated with the reduction.”

Lifestyle of Pieralapithecus Catalan

This ancient primate is believed to have weighed between 30 and 50 pounds and had features similar to modern apes, suggesting a possible common ancestor.

Its broad, flat chest, rigid lower spine, and unique wrist features suggest climbing ability, suggesting a transition from once arboreal primates to primates that could move both in trees and on the ground.

The structure of the skeleton suggests that Pierolapithecus catalaunicus had a short, broad body, as well as mobile shoulder joints. This suggests that it was good at climbing and swinging in trees, a movement known as brachiation. However, its intact finger bones suggest that it also spent a lot of time interacting with the ground.

Face the facts

Its facial structure is also quite telling. Its forward-facing eyes, short snout, and small canine teeth set it apart from primates that eat only fruit, suggesting it had a diverse diet. These features paint the picture of an adapted creature that lived both in trees and on the ground.

Pierolapithecus overturns previous ideas about evolution. Its existence suggests that basic hominid traits may have emerged earlier than scientists once thought.

While not a direct ancestor of humans, it offers a clearer picture of the lineage that led to great apes and humans, and highlights traits that evolved as primates adapted to changing environments.

Why is Pierolapithecus catalaunicus important?

The discovery highlights that hominid evolution was not a straight line, but a branching tree with many extinct relatives.

Every new fossil discovery, like Pierolapithecus, adds another piece to the puzzle, helping us understand where we come from and perhaps where we are going. Unfortunately, the site where Pierolapithecus was found is at risk of illegal excavation and vandalism.

Conservationists and scientists are calling for increased protection to preserve this invaluable window into our past. As we continue to study Perolapithecus, it is imperative that we preserve these archaeological sites to keep our shared history intact.

So what does all this mean for us?

Finds like Pierolapithecus catalaunicus help fill gaps in our understanding of primate evolution, highlighting the complexity of the human evolutionary tree and the intricate path that shaped life on Earth.
