Endocrine System Evolution — Saying It Makes It So!

One of the most common explanations offered for the existence of complex systems, whether in biology, the cosmos or other areas, comes down to "Evolution Did It". No wonder people are confused about evolution, it is assumed by faith and then presented as a scientific fact!

For example, the endocrine system is an amazingly system of regulation in the bloodstream. Hormones are released, and a kind of cell-to-cell communication takes place. Cells that are not targeted are not involved. The explanation is that it evolved that way.

But how? What is the mechanism? Is there any evidence, or is it just an evolutionary worldview that is asserted? Instead of depending on time, chance, mutations and guesswork, creationists already know that such intricate marvels are evidence of the Creator's work in action.

A student of zoology would be surprised to learn that, although researchers know much about the function of our endocrine system, they know essentially nothing about its supposed evolution.

The creationist sees the incredible detail of the living world as part of God’s plan, purpose, and special design. Indeed, the various systems (e.g., digestive, muscular, circulatory, endocrine, etc.) of the human body working together is calledhomoeostasis, meaning the body is designed to maintain itself in a state of stable, healthy equilibrium.

The endocrine system is a complex arrangement of ductless glands that secrete hormones into the bloodstream. Hormones are regulatory substances (i.e., chemical messengers such as insulin and prolactin) produced by specially designed cells and are effective in low concentrations. As you read this article, dozens of hormones are flowing in your bloodstream—and these hormones are designed to impact only the cells that have special receptor molecules on their surfaces. If the matching receptor molecules are not on a given cell’s surface, the corresponding hormones do not affect that cell. Most of these receptor molecules are called G protein coupled receptors. God designed them to “sense” molecules (such as hormones or odors) outside the cell and activate special pathways inside the cell, resulting in a specific response.
