So you go from a specific example (bacteria) to an unproven generalization when you cannot disprove your example (bacteria) is speciation or evolution within a species. Also, what makes sense to you is totally illogical to others.
You brought up climate change, which covers a lot of area. There is seasonal climate change where all organisms adapt or die. Plants that do not "survive" (annuals) come back due to seed production, while perennials go dormant. Then there is catastrophic climate change, which caused the extinction of dinosaurs.
You also referred to "traits". Intelligence is a "trait" has as much to do with environment as genes.
However, lets stick to your example.
