#SnailKites (#Schneckenbussarde) in #Florida beweisen: #CharlesDarwin hatte wieder einmal Recht mit der #Evolutionstheorie.

Als sich die #Schnecken--die Beute der #Schneckenbussarde--weiterentwickelten und 5x größer wurden, taten dies auch die #Beutevögel:
ihre Schnäbel wurden ebenfalls größer, ebenso wie ihre Körper, letztere um 12%.

Eine ähnliche Anpassung wurde bei einer anderen...

#SnailKites in #Florida Probe #CharlesDarwin was right about #Evolution once again.

When #snails--the prey of #SnailKites evolved and got 5x bigger, so did the the #BirdsOfPrey:
their beaks also increased in size, so did their bodies, the latter 12%.

A similar adaptation by another species of #birds had been observed on the #GalapagosIslands.

"#SnailKites, as you might have ingenuously guessed from the name, eat #snails! #AppleSnails (Pomacea spp.), to be precise. #Trematodes in the Cyclocoelidae family use snails as their hosts for the larval stage, meaning when those snails are eaten, little baby trematodes get to grow up into a mature adult in the body of whatever ate the snail (usually birds)."
