Ok, I guess my first question is: There are Christian gyms? Say what? What else am I missing out on, Christian cars and Christian computers?
Second of course would be: Are you serious? Because this sounds awfully similar to the "my granddaddy wasn't a monkey" argument from creationists.
For those who don't have Time,
this would be the article right?
The thing about speciation is that all currently living species can be traced to extinct ones, and as such, pick any two species and they share a common ancestor. So yes,
homo sapiens and
Tiktaalik roseae can ultimately be traced back to a common ancestor. Are we cousins? Not really. Tiktaalik was around 375 million years ago, humans have only been around for about 5 million years. That's an extremely distant relationship.
The reason why it's important is that the fossil represents a transitional with both fish and tetrapod characterists - demonstrating that fish did indeed evolve the characterists which would later give rise to terrestrial species like amphibians and reptiles. It's the "missing link" that creationists have been asking for, and it was found precisely where scientists predicted it would be found. Not bad for "just a theory", eh?
Now about the cousin part. Why would you find it laughable that species are related to one another through common descent? Is this just an emotional reaction - being compared to something that one doesn't highly regard taken as an degrading insult? Does the fact that humans are related to other species somehow diminish humanity or make humans seem less special?
Because if that's the reason, why stop there? Heliocentrism means that the Earth is not the center of universe and more and therefore that humans are not the center of importance in the universe, so it must be wrong.
"Who will venture to place the authority of Copernicus above that of the Holy Spirit?" -John Calvin
And yet heliocentrism can and does coexist with Christianity, just like evolution:
"This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being." -Isaac Newton
