Yes, but that doesn't matter because if you have enough offspring some will survive
and the gene doesn't care which particular individual it uses to get into the next
generation. There is no way immortality could come for free, it would take work, and
all that work would be wasted if you're eaten for lunch when you're only 6 months old.
The genes have "decided" that in a dangerous world finite resources could be put to
better use, such as growing fast and having lots of offspring and having them early
in life. The more dangerous things are the sooner you want them.

I think that's exactly why evolution never thought it was worth the bother to
come up with an immortal animal. Why do you think that explanation for aging
