Plenty of people predict that increased antibiotica use will lead to a raise in antibiotica resistance among bacteria.
Organisms like bacteria that have much more iterations behind them then humans also tend to have less waste in their DNA.
Grasses beat trees at growing in glades with animals that eat plants. Why? Grass has more iterations behind them and is therefore better optimized for the enviroment than the trees.
A tree has to get lucky to survive the beginning. If it surives the beginning it can however grow tall and win.
Let’s say you keep the enviroment stable for 2 billion years. Everything evolves naturally. Then you take tree seeds and bring them back to the present time. I think there a good chance that such a tree would outcompete grass at growing in glades.
Most “predictions of evolution” that can be found online are more about finding past evidence of common descent (e.g. fossils) rather than predicting the future path that evolution will take.
Fossils don’t really get used as the central evidence of common descent anymore. These days common descent usually get’s determined by looking at the DNA.
In my experience people who discuss evolution online that do focus on fossils are usually atheists who behave as if their atheism is a religion. They think it’s important to defend Darwin against the creationists. On the other hand they aren’t up to date with the current science on evolution.

You seem to be predicting that grasses have smaller genomes than trees, but wheat is famous for having a huge genome. Here’s a table of a few plants. Maybe wheat is an outlier and I’d be interested if you had documentation of some pattern, but I’ve always heard that there is none.
Do you have evidence that the variation in genome size among multicellular organisms is not variation in waste? Added: As far as I know, the consensus is that it is. If you disagree with the consensus, you should acknowledge that’s what you’re doing.

I haven’t made a claim that strong. To the extend I made a claim it’s not all variation in genome size between multicellular organisms is due to different amount of waste.
And no I don’t intend to claim something that’s out of consensus in this topic. To the extend I might differ on this topic from consensus consider that to be errors.
If I remember right then one reason for plants like grasses to have long genomes was to have multiple copies of genes to speed up protein production.
What do you mean, “predict”? It has been empirically observed, a lot.
cousin made the claim that we can only say something about evolution that happened in the past. I say that we can confidently predict that increasing antibiotica resistance among bacteria will continue in the future.
Huh? It doesn’t work like that at all. For one thing, the “environment” isn’t stable.
Firstly describing complex system in a ew words is seldom completely accurate. The question is whether it’s a useful mental model for thinking about it.
In this case the idea I wanted to communicate is that it’s very useful to think about the speed of iterations and the competitive advantage that a specis gets by having as advantage of hundred of millions of iterations over their competitors.
The enviroment doesn’t have to be stable for the argument that I made. In changing enviroments a spezies with faster iterations adapts faster. A lot of genetic adaptions are also about housekeeping genes that are useful in most enviroments.
Bacterial cultures taken of sick people introduce microevolutions by trying to grow bacteria in several different antibiotic environments. Doctors try to use antibiotics that cause dead ends in those evolutions. I’m not sure how much time mutation has to happen in vitro, though.

If you want to be exact I didn’t say genome size but waste. Through mutation inactived genes, retroviruses and so on. It takes time to remove them.
