[Avodah] eye pains on shabbat

[Rich, Joel]

But some of the biological cases could be a change due to changes in diet or breeding than in genetics or theory. The possible change of the size of an olive which was called nishtaneh hateva, could be because we bred a slightly different strain of olive. Or chicken, yeilding different chicken-egg sizes. Or that mothers are healthier with today's nutrition and medicine, and therefore 8th month babies are more likely to live.

So we have three senses of the term on the table:
1- RAbhR: theory changed
2- The population changed due to breeding, nutrition and medicine
3- The biology changed

R' Yaakov Menken (of torah.org) noted to me in a discussion that nishtaneh hateva in the usual sense (I think #3 is the one most contemporary observant Jews assume) is belief in evolution.

Tir'u baTov!

4. For the non-philosophical types, something changed , I don't really know or care what, as long as it allows me to not have cognitive dissonance (I'd say this is the one most contemporary observant Jews assume)
