Oops! He’s really stepped in it now! That is a giant no-no thing to admit in YEC circles. Only the imagined boundaries of their ill-defined Genesis kinds allow them to claim that any changes we see are not really “evolution”. On the other hand, it may be one of the few things Robert may have a point about. After all, it’s possible to interpret the phrase “after their kind” in Genesis in a way that does not restrict how far kinds can change. It could be taken to just mean that God created a set of different “kinds” that bred with each other and not other kinds, but that each still had the capacity to change in essentially limitless ways as they adapted to new environments over time (in other words evolve, and in major ways). YECs seem to never consider that, even tho it is still in a sense “literal”–in the same way that the Hebrew word for day can literally mean a 24 hour day, a longer period of time, or an indefinite period of time (as it is used in other places in the OT, and even in various parts of Genesis), They also seem to never consider the implications of the verses in Genesis where God commanded “let the sea conceive and bring forth…” and “let the earth bring forth” living things. To me, that sounds more like an indirect creation (evolution) than direct and instant creation. Yet they insist on the latter, apparently unwilling to consider that they could be mistaken, despite all the fossil and geologic evidence for a long and complex earth history.
