Yet is that an example of design or another example of simple evolution.

Dull answer but what it actually is is an example of what happens if a system is designed, then left to go to pot. What's happening is that when there's a fault it's faster and cheaper to run a new cable leaving the original in place than attempt to find and fix it.

The thing about science is that it's all published. Anyone can research what is known about almost any scientific idea. These days you just type a phrase into google like “the evolution of lactaion” or “the evolution of the mammary gland” and then look for a good scientic source. Here's the first one I found

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2688910/

You'll see that it's headed “The origin and evolution of lactation” and it's published in the Journal of Biology which is a great start. It's also not behind a paywall and it's not highly technical. So there you go, easy. If you read that you'll find out what we know and you'll also find out that Darwin was wrong about it.

(I suspect that your creationist sources picked lactation - as well as the eye - to talk garbage about because 150 years ago Darwin mentioned them. Science moves on, discovers more and knowledge increases; dumb ideas never change it seems.)

What you do is read some antique garbage on a creationist web site, half understand it and post a one-liner here looking for a reaction. You're not remotely interested in what we actually know about the evolution of lactation are you? You won't even read that paper will you? You'll just bugger off without answering and return in a month spouting more bollocks about flagella or some such, having learned nothing but feeling smug inside your ignorance.

It's not a record by any means, but there are few that rise to your level of obvious, consistent, repeated and easily proveable idiocy.

[quote]All male and female mammals have mammary glands, which is the organ that produces milk. When mammary glands mature fully in females during puberty, they develop into a state where a hormonal spike—most notably of prolactin—can easily induce lactation. For males, the gland generally doesn’t mature to that level.

So the difference is a matter of hormonal influence, first during puberty and then again after pregnancy. Men do have the necessary equipment, but usually they don’t naturally produce the necessary levels of hormones to use it. Provide the right hormones, though, and male lactation is absolutely possible.[/qs]
