Raising a child from the Paleolithic era in the present day would certainly be an extraordinary challenge and experiment, both ethically and scientifically. If this were somehow possible—and setting aside the complex ethical implications—there is potential for the child to adapt, but the degree of adaptation and the challenges involved would be significant. Here are some considerations:

1. Biological Adaptability: Humans from the Paleolithic era were Homo sapiens, the same species as modern humans. Therefore, the child would have a similar brain structure and genetic potential for learning and adaptation as contemporary children. Assuming there have been no significant biological changes that would affect the ability to adapt, the Paleolithic child might have the plasticity to learn and grow in new environments, as this is a characteristic trait of our species.

2. Language and Communication: One of the biggest adaptation hurdles would be language acquisition. However, children have a strong ability to learn languages, especially at an early age. If the child is quite young, there’s a good chance they would fully acquire the language(s) spoken around them, though it might take longer than for a contemporary child due to a lack of early linguistic exposure relevant to modern languages.

3. Socialization: Human societies have evolved dramatically since the Paleolithic era, and the social norms, behaviors, and expectations are utterly different. The child would need to be socialized from scratch into modern society. This could prove difficult, especially if the child had already begun socialization in their original context, but it is not impossible.

4. Immunity and Health: The Paleolithic child’s immune system would be used to a completely different set of pathogens than those prevalent in the modern world. This could pose a risk to the child initially, but with modern medicine and vaccinations, these risks could potentially be managed.

5. Cognitive and Educational Challenges: Education today is vastly different from the informally transmitted knowledge of the Paleolithic era. The child would face significant challenges in adapting to structured learning and abstract concepts not relevant to their original context. Nonetheless, the cognitive flexibility of children suggests that the child would be able to learn and adapt with proper support.

6. Psychological Stress: The child would be subject to considerable psychological stress, being uprooted from their time and place, without any familiar faces, environment, or culture. They would require sensitive and expert psychological support to cope with such an extreme transition.

7. Ethical Considerations: Modern ethics would almost certainly prohibit such an experiment. The welfare and rights of the child would be a primary concern, as well as the impact on their psychological wellbeing.

In summary, while it is plausible that a Paleolithic child could adapt to some extent to modern society with the right care and support, the process would involve significant challenges on multiple fronts. Given that this is a purely hypothetical scenario, it’s also worth noting that we can only speculate based on our current understanding of human adaptability and development.
