Early tetrapods had surprisingly stiff necks, study finds
Original: Early tetrapods had surprisingly little ability to move their necks
New research indicates the earliest four-limbed land animals had far less neck mobility than scientists long assumed. The finding, reported via EurekAlert!, suggests the transition from fish to land vertebrates involved more rigid head and body connections than previously believed, reshaping ideas about how these pioneering animals fed and moved on land.
Why now: It challenges long-standing assumptions about a key stage in vertebrate evolution.
