Last night was the fourth and final episode of Channel 4’s Inside Nature’s Giants series. On this show they dissected an adolescent giraffe. It was just as interesting as the previous shows.
They showed the incredible muscles of a giraffe’s neck, and the massive ligament that holds their head aloft (its natural position: it’s actually an effort for them to lower it).
They showed how evolutionary legacies like the laryngeal nerve are clear evidence that we are certainly not intelligently designed.
They showed how massively muscled a giraffe’s heart is to pump blood all the way up that neck (and how there are valves in its jugular vein to prevent too much blood pressure in the head when it lowers it to drink).
Well done, Channel 4. This was a great nature series.
