Monarch Butterflies 2018 : Part 7 (Miniaturisation)

When a caterpillar emerges from it's tiny egg, it's so small you can only see it if you have amazing eyesight or a magnifying glass. Yet from the get go, it knows how to move around without falling off and has immediate dexterity. It understands the need to eat and gets on with that. It sheds two skins as it grows and at a certain point knows it has to create a latch point to hang from.

It then becomes a chrysalis, an amazing transformation in itself as it wriggles to shed the striped skin. It then settles down to hang for a while. When in this state, how does it turn into a butterfly? Quoting Scientific American:

First, the caterpillar digests itself, releasing enzymes to dissolve all of its tissues. If you were to cut open a cocoon or chrysalis at just the right time, caterpillar soup would ooze out. But the contents of the pupa are not entirely an amorphous mess. Certain highly organized groups of cells known as imaginal discs survive the digestive process.

Once a caterpillar has disintegrated all of its tissues except for the imaginal discs, those discs use the protein-rich soup all around them to fuel the rapid cell division required to form the wings, antennae, legs, eyes, genitals and all the other features of an adult butterfly or moth.

If that isn't something beyond comprehension, I don't what would be. What controls the process of that soup like substance to start turning into body parts that will work in superb precision with its tiny brain is amazing. It is not taught how to use its parts to fly, navigate, find food, mate and know where to lay eggs. It's all inside the programming inside the tiny creature that emerges from the tiny egg. Here is a picture below of a young caterpillar. The creative genius behind this cannot be from a random accident.

Can you see it? Look closely at the green seed sack
