The giraffe stature is not explained by evolutionary ways

 

Joel Kontinen

Biologists and physiologists have long been interested in the suite of adaptations associated with the extreme stature of the giraffe. Their unusual anatomy is thought to provide various selective advantages, as was though by Lamarck and Darwin. .  

 

The okapi (Okapia johnstoni) is a living fossil and the only other extant member of the Giraffidae family and provides a useful point of genomic comparison, but they did not grow as tall as giraffes, and nothing in this present discourse says that the giraffe caught its elevated structure mutations or other evolutionary ways.

The deep sea is full of wonders. (See examples here and here.)

It looks like an eel,(which is a living fossil), but it isn’t. The blue dragon fish is small, weighing circa 2–50 cm (0.8 –20 inches).

They don’t like the surf; they usually are found at a dept of 1,500 metres in the Pacific, Atlantic, and Indian oceans. they visualise their prey with the help of glowing barbels.

A Barbel ”is a slender, whiskerlike sensory organ near the mouth.” It known to migrate vertically whilst capturing its prey.

Everything the Lord made beautiful.
