Tiny Archaeopteryx Reveals Soft-Tissue Feats That Confirm An Ancient Flight

Scientists analyzed the Chicago Archaeopteryx fossil, a pigeon-sized specimen from Solnhofen limestone, using CT scanning and UV light to expose preserved soft tissue and long wing tertials. The find provides clear evidence that this early feathered creature could fly and reinforces Darwin’s 1859 prediction that transitional forms would appear in the fossil record, refining our understanding of how flight evolved in dinosaurs and birds.

Tiny Archaeopteryx with preserved soft tissue reshapes view of bird flight origins

Chicago’s Archaeopteryx fossil, unusually well-preserved with soft tissues, was CT-scanned and examined under UV light, revealing detailed anatomy from snout to tail and long tertial feathers. The findings suggest this bird could fly and imply that flight evolved more than once among dinosaurs, lending fresh support to Darwin’s theory of evolution.

"12,000-Year-Old Preserved Human Brains Challenge Soft Tissue Decay Assumptions"

A global archive of over 4,400 preserved human brains, some dating back 12,000 years, has provided groundbreaking insight into soft tissue preservation, challenging the perception that naturally preserved brains are extremely rare. The brains, originating from various environments worldwide, were found to have been preserved through mechanisms such as dehydration, freezing, saponification, and tanning. This research could offer valuable information on human evolution, ancient health, and diseases, including neurodegenerative conditions like Alzheimer's. The study highlights the need for excavating archaeologists to remain open to unexpected discoveries and emphasizes the scientific value of studying these preserved human remains.
