But the proportion of tuskless elephants has increased [dramatically] in some populations."

They are on the way to doing that. A graph shows how much the population is growing back.
I have also heard that sea fish are getting smaller and becoming sexually mature at smaller sizes. Because of course we fish for them with nets, and smaller fish pass through the mesh.

That is fascinating ... clever sea fish living their lives with natural selection.
...hunting has clearly eliminated the big-tusked elephants.

Contributing to their endangerment, all males still have tusks.
