so hmm. what can cause these biological changes?
environmental changes.
choice in mateing.
choice in habits.
mutations.
disease/microbes (or whatever i mean by that lol i think you know.)
all living things are subject to these things, and over time all things adapt and change by these things.
You shouldn't make absolute statements like this. When you say that it is
all living thing, then you only need one example of a living thing that is not subject to those things to refutue your statement. You should say
most, and then not base your arguments on absolutes.
Plants can have no choice in their mate nor their habitat and so can some animals like sponges or coral.
would it be wrong then to say that since stars change in timely manners based on environmental changes, that it could be considered evolution?
In the vaguest sense, evolution is just change over time. Seeing as it is pointless to have a whole thread devoted to that, it seems that Phat is talking about defining
biological evolution.
