Anyone with a slight knowledge of biology knows that the human heart, lungs, kidneys and brains are exquisitely designed.
Anyone with a slight knowledge of biology knows that the human heart, lungs, kidneys and brains are products of hundreds of millions of years of biological evolution.
You must be trying to kid me to say that evolution answers the appearance of design issues.
And yet, it does.
I find it laughable that intelligent scientists are so fixated on the evolutionary methodology that ScienceDaily can report: 'Researchers are providing a new explanation as to why
life remained as little more than slime for a billion years, before rapidly diversifying in the 'Cambrian explosion of life' (
source).
Life was a lot more than slime prior to the Cambrian. That's a nice pop-science article, but the truth is a lot more complicated. Trace fossils indicate animal predator/prey relationships stretch back at least 750 million years, and possibly as far as 1.2 billion.
The pre-Cambrian (Ediacaran) biota were diverse, including at least eleven different phyla (some of which are no longer existent), and all sorts of interesting creatures. There were the protoarticula, giant protozoans, various bag/blob lifeforms, siphonophores, rangeomorphs, erniettomorphs, cnidarians, worms, and soft-bodied proto-arthropods. All at 560-540 million years ago.
What's really cool is that some of the Ediacaran biota may have lacked the Hox genes, which regulate bilateral symmetry. So they're asymmetric.
New Ediacaran fossils are quite rare, as most are soft bodied, meaning that they didn't preserve very well. Cambrian life features hard shells, which means they're preserved with much greater frequency.
There are a couple of reasons why we see an 'explosion' at the onset of the Cambrian. There was a mass extinction, which opened up a lot of niches to new exploitation. There was a new evolutionary innovation (hard structures), which opened up new niches AND started an 'arms race'. There were new environmental conditions that opened up new ecological niches.
Rapid morphological radiations aren't that unusual in the history of the planet. Its just that the Cambrian is the best known, the most diverse (possibly) and still mysterious (as evidence remains fragmentary, because we're dealing with an event that happend more than 500 million years ago).
We have that choice OR human beings are made by God in his image. I know which evidence I'm going with.
I'll go with the one that doesn't start by assuming its conclusion, and then working backwards from that, distorting painstaking research into the natural world done over nearly two centuries.
