as i mentioned in the first post i am an evolutionist..
As i read creationists claims about Irreducible Complexity i got puzzled.
let's look on the following Irreducible system:
The problem only gets complicated to explain,
if we look on the suckle reflex in mammals, a friction sensors on the mother nipples sense the infant sucking, as a result a signal is being sent via neurons from the nipples to the hypothalamus in the brain. after the signal has been processed a signal is being sent to the hypophyses gland.
as a result the hypophyses gland releases two hormones to the blood stream.
the two hormones travels in the blood stream until they reach a specific receptors in a specific cells membranae in the milk glands.
this results two things:
1. the milk is being squeezed.
2. the milk reproduction process is being accelerated.
the process could be read here:
Human Milk and Lactation: Background, Physiology, Human Milk and Preterm Infant
how could this 'irreducible complexity' system be reduced?
each factor is important for this system evolution, the friction sensors is important, the neurons connection to the hypothalamus, the process in the hypothalamus, the signals which is sent from the hypothalamus to the hypophyses gland, the metabolic process which results the manufacture of the two hormones, the proteins in the receptors in the milk glands. and the special processes which accurs after the hormones reach to this receptors.
and all the parts of the system is a result of many genes working together, why would each part develop if another part didn't existed?
why would a friction sensors develop in the nipples if the link between the hypothalamus and the hypophyses didn't existed?
and if the receptors didn't existed? and if the hormones didn't existed?
if the whole course didn't existed why would any of the parts develop separately?
