This was the title of an article on the Fox News web site. You can read the entire article here.
When you read the article you discover that they did not discover the origins of the human nervous system. Articles that deal with evolution are very dishonest in this respect. The title always states something that has been discovered that purportedly supports evolution but then when you read the article closely and with scrutiny you realize the title was misleading. The title normally reflects what they want to discover, and hope to discover, not what they actually discovered.
But they can claim in the title that they have discovered the origins of the human nervous system and then unthinking people read the article with that bias and see the discovery as evidence of the premise set forth in the title.
"The study found that sponges contain about 25 genes that are very similar to human genes found in the synapses of nerve cells."
This is what they discovered. This is not what the title says they discovered. They are not even the same genes but very similar. Things that are very similar are not the same.
"The surprising discovery, detailed in June 6 issue of the open-access journal PLoS ONE, suggests the evolutionary origins of the nervous system are much older than scientists previously thought."
"Suggests" is the word that should stick out in this sentence. Why does it suggest the evolutionary origins of the nervous system are much older than scientists previously thought. It suggests it because they want it to!
"Sponges are the first animals to branch off compared to the rest of animals."
A premise (evolution) that has yet to be proved, but stated as fact proven by empirical science.
"Not only do they have [human synapse genes], they also have this signature that they may be functioning in a similar way in the absence of a nervous system, as they do in the presence of one,"
I suppose then that they may not be functioning in the same way. May be is speculation and the speculation is used to give us the declarative statement found in the title of this article.
"The function of the sponge genes are not clear,"
Then why is the declaration in the title so clear????
"Scientists think the first true neurons and synapses first appeared on Earth more than 600 million years ago in organisms called cnidarians, which today include the hydra, sea anemone and jellyfish."
And of course when scientist think that automatically makes it authoritative! They think, they do not know. But the title suggest that they do know.
"The researchers speculate that the sponge genes were recycled over evolutionary time, with small modifications, to create the nervous systems of later animals."
Evolution is built on speculation. The title of the article does not reflect any speculation. All researchers have to do is speculate and the rest of us are to bow before their superior intellect.
""Evolution can take these ‘off-the-shelf' components and put them together in new and interesting ways," said study leader Kenneth Kosik, a UCSB neuroscientist."
And how does he know this? I can tell you that is is based upon more suggestions, speculation and thinking, but not hard evidence.
"Other genes would also have had to evolve or to have been co-opted to create complex nervous systems, such as our own."
And is there any evidence; not speculation, thinking, and suggestions, but evidence that this has happened.
Scientists think an estimated 77 to 1,000 genes are important for human synaptic communication, Oakley said."
Again scientist are thinking! The fact is they do not know.
Summary: the title of the article reflects that they have discovered something that they have not. The article simply relates what they think, and speculate, and suggest may have happened. It only tells us one thing they know.
"that sponges contain about 25 genes that are very similar to human genes found in the synapses of nerve cells."
From this one piece of evidence they dogmatically conclude in the title that they have discovered the origins of the human nervous system.
Does arrogance and presumption achieve any higher level than among evolutionist??
