That's one retarded idea you've got there.
No. They are extinct because they were not well enough adapted to the world and it's current state.
Retarded idea eh? Too bad for you because it's genius and they've already done it to a unique frog that went extinct in 1816.
and there's many other reasons why a species can go extinct other than that.
Pointless IMO. We have no idea how an extinct species would react to a different environment. It could have devastating effects on the ecosystem.
That's a good point, but think about certain animals that go extinct in the future because of humans(poaching ,etc.). There's actually many good things that this can be used for like for example bringing life to other planets.
That almost rustled my jimmies. I'm well aware of how science will move forward but as a final product there's little to no point to bring dead species back to life.
I won't rustle your jimmies. I'll fucking rip them.
No there's still some point. It allows scientists to better understand the fundamentals of how that animal lived. It's not really bringing them "back to life", it's more like altering the genes of its descendants to give birth to its ancestors. This allows us to protect biodiversity and genetic diversity. Not only does this undo the harms that humans have done, it also restore ecosystems as certain animals that were extinct contribute a major role in how the ecosystem functions. Once then, we will be able to prevent any further extinctions.
