Evolutionary Adaptations Forced by Climate Change

I don’t see how evolution can take place in a bucket in a cooler. My understanding of evolution is that successive reproductions produce a genetic change that results in a plant or animal changing it’s genetic structure. This seems to be more an adaptive ability that was already present in the mustard plant that allows it to adapt to different climate conditions within a certain range. Their are many of these adaptations in nature. Coyotes will have larger litters when there is an explosion in prey animal populations. Conversely smaller litters when prey is scarce. How does the coyote know there are more or less prey animals in any given season? Obviously there are some things about evolution we do not understand, but I am having trouble believing that evolution took place during the conditions the mustard seeds were stored in.

nobody said the ones in the cooler changed, they suggest the ones in the field now are different from the ones in the field then.
