Let stick with crystals. When you use words like “replicate”, are you referring to an increase in the mass or just a change in the structure? So when chemicals such as salt or sugar crystalises, would you consider them a living thing? You don’t! Because you know they are lifeless elements. They change shape not because they are alive.The same goes for biological tissue…
Ever tried to breed bacteria without water? Or without proteins?
How would your gametes do without the machinery in your body?
Things replicate under particular conditions.
Remove those conditions and they stop replicating. One part of the evolution theory in a nutshell. The extinction part.
Do crystals know how to self-replicate?
Are non-living carbon-based self-replicators that far-fetched?
Bacteria is a different animal together. They live and die. They multiply.
I’m sorry , you haven’t proved that this line is bogus.Start at number 1?
“Lack of a viable mechanism for producing high levels of complex and specified information. Related to this are problems with the Darwinian mechanism producing irreducibly complex features, and the problems of non-functional or deleterious intermediate stages.”.
I really hope you don’t take what he wrote in the book seriously. For example:This book (The blind watchmaker, by R. Dawkins) addresses the problem… it may even address a few others in that page made for creationists… referencing “articles” from the “discovery institute”…
“how long would we have to wait before random chemical events on the planet, random thermal jostling of atoms and molecules, resulted in a self-replicating molecule?”
“This is that, once life (i.e. replicators and cumulative selection) originates at all, it always advances to the point where its creatures evolve enough intelligence to speculate about their origins.”
“Given our ration of luck, we can then ‘spend’ it as a limited commodity over the course of our explanation of our own existence. If we use up almost all our ration of luck in our theory of how life gets started on a planet in the first place, then we are allowed to postulate very little more luck in subsequent parts of our theory, in, say, the cumulative evolution of brains and intelligence.”
“… once cumulative selection has got itself properly started, we need to postulate only a relatively small amount of luck in the subsequent evolution of life and intelligence.”
“Suppose we want to suggest, for instance, that life began when both DNA and its protein-based replication machinery spontaneously chanced to come into existence.”
He tells you that all you need is luck and plenty of time and voila DNA and its protein-based replication machinery spontaneously chanced to come into existence. He doesn’t address the starting point. He jumps straight to living matter. Or straight to matter containing DNA and stuff. That sound scientific to you? Not much different from my Ferrari example. May be I was too optimistic, change that to a bicycle instead.
And your point being? I wasn’t expecting anything.Have you seen the “fossils” of those early bacteria?
I have… they’re not what you’d expect. Go look them up.
And, from that very feeble kind of fossils, we then “leap” to fossils of animals with a shell… something that is hard enough to withstand the process of fossilization.
You sound like Dawkins. Things leaping from nowhere for no reason. That doesn’t sound like the scientific method. Back to the same old question: where did the information to “leap” comes from? Bacteria doesn’t need a shell to be fossilised. Bacteria doesn’t contain information on how to “leap”. Or how to change itself to some other species. Or how to change body plans.Not unsurprising, if you ask me.
Darwin say we should find gradual changes in evolution. We didn’t.What do you expect to find that isn’t there?
Soft bodied slug-like aquatic creatures that were buried by some dirt and got fossilized?
oh… news.discovery.com/animals/earliest-known-animals-120628.htm
We are talking from paleontology viewpoint.In early organisms, mostly microbial, that is an eternity!
It doesn’t matter. We are not very concern about microevolution. It is a given. Microbes after millions of cycles are still microbes. They do not mutate to become a bird, or a fish or a worm or an insect. The difficult part is macroevolution. That is where the fossil problems lie. That is where Darwin Tree of Life comes falling down.
