Nouvel article par Erik A. Meilak @University of Southampton avec @paulineprovini.bsky.social #MECADEV sur la fameuse question de l'envol d'Archaeopteryx.

Archaeopteryx BOUNCED into the air! Our new paper in @devbiol.bsky.social shows the first bird used multiple leaps (like modern crows) to take off, using today’s birds to unlock how flight evolved 150M years ago! 🔗Read more here: www.sciencedirect.com/science/arti... #DinosaurBird #HowFlightBegan

The title is "How did Archaeopteryx take off?"

There are 3 boxes:

1. Modern birds can leave the ground with a single leap, followed by powerful wing strokes which is a very energetic behaviour

2. A 400g Archaeopteryx, not as 'advanced' as modern birds, could have become airborne by making a jump with a flap, followed by another hump and subsequent flapping to achieve stable flight at 7m/s

3. This low energy take off is used by modern birds when in hurry to take off.

The results of a study by Erik A. Meilakab et al. show that the earliest bird, Archaeopteryx (a 150-million-year-old reptilian bird), could have reached its minimum sustained flight speed in just two to three jumps, without the energetically demanding single jump of modern birds. 1/2
