Words like 'earlier than thought,' 'most fossilized remains,' and 'significant breakthrough' reflect the tone of admiration and scientific curiosity, highlighting both the novelty and importance of the findings.
Most posts highlight the importance of the fossil discovery, emphasizing that it supports earlier theories about the group's evolution and divergence times.
The posts consistently express fascination with the fossil's age and its implications, showing high curiosity and engagement with the evolutionary details.
Discussions include specific scientific findings such as the physical features of the fossil and its significance, indicating moderate to deep engagement.
Many posts frame the fossil as a significant breakthrough that changes understanding of flying squirrel evolution, suggesting high impact on the scientific field.
Abstract in brief
- The discovery of the oldest fossil skeleton of a flying squirrel, dating back 116 million years, provides new insights into the evolution and divergence time between flying squirrels and tree squirrels.
- Previously, identifying extinct flying squirrels relied mainly on dental features, which are not unique to this group, leading to possible misclassification; this new fossil offers more definitive physical evidence.
- Phylogenetic analysis combining physical and genetic data suggests that flying squirrels have maintained their form with little change for nearly 12 million years, and their divergence date is older than earlier molecular estimates, around 23 million years ago.]
