A groundbreaking study published in Current Biology has revealed that Neanderthal infants, specifically the Amud 7 specimen discovered in a cave near the Sea of Galilee, Israel, experienced rapid growth, reaching toddler size within just six months. This research, led by a team from Ono Academic College in Israel, utilized advanced 3D reconstruction methods to analyze the skeletal remains of the Neanderthal infant, which lived between 51,000 and 56,000 years ago. The findings challenge long-held beliefs about Neanderthal development, showing that their body and brain growth rates were significantly faster than those of modern humans. The study found that while the infant's dental age indicated it was approximately 5.5 to six months old, its skeletal structure resembled that of a 12-14 month old human child. This rapid growth likely provided Neanderthal infants with advantages in conserving heat and becoming independent sooner, a necessity for survival in the harsh conditions of the Ice Age. Researchers identified three distinct phases of Neanderthal development, noting that while they grew rapidly in early childhood, their growth patterns began to align with those of modern humans by age seven. The study suggests that differences in gene expression, rather than genetic makeup, may explain the divergent growth patterns of Neanderthals and Homo sapiens, with Neanderthals evolving for speed and strength, while modern humans developed a longer childhood for cognitive growth.
