So before I go to bed (it is 22:56 here in the UK) I thought I’d post this interesting BBC news article about a landmark cancer study (studies?) that folk may find interesting:
And also a question. Are cancers examples of one thing evolving into another thing? One of the common objections to evolution I rasied in my YEC days is that one species does not become another. Dogs produce dogs; cats cats; rats rats, repeat as desired.
However, it struck me that the change that takes place when, say, a skin cell turns into a skin cancer cell seems so dramatic a mutation that is it fair to say that it is still a skin cell? Doesn’t the mutation that takes place within the skin cell change it into something comparable to a new species when it becomes a skin cancer cell? In that sense is the change of a cell into a cancer cell a good example of evolutionary mechanisms in action? Why/why not?
As you all know, I’m not a biologist so please forgive my faltering use of language in attempting to explain what I meant. Hopefully, it makes sense. Particularly, welcome @sfmatheson thoughts and expertise on this one.
[Gracious] thoughts and/or course corrections welcomed.
