Really? Could you please point me to the particular Bible passage where this definition is offered?
The boundary then is drawn where fertilization ceases to occur.
The problem with this is that biologists also have a term for this. It's a "species boundary." Which has nothing to do with the Bible (in fact, it didn't even derive from it).
... but evolution has also been observed that crosses the species boundary. Meaning that evolution can cross "kinds" if you use "kind" as a synonym for species.
Now according to science can an ape and a human produce? According to the Bible they can't. Which one is right.
How can you ask "which one" when you've only given one alternative?
Science says that an ape (let's say a gorilla for specificity) and a human cannot interbreed (they are different species) but that they come from a common ancestor.
The Bible says that an ape and a human cannot interbreed.
Which one is true? Well, at this level of detail, both of them.
Of course, if you misread the Bible to say that an ape and a human cannot interbreed and that they share no common ancestors,.... well, in this case, the Bible does contradict science. But in this case, the right one is probably science. It's certainly the one that's supported by more evidence.
