Learn English – How to say “it’s actually the opposite” in a single phrase

phrase-requestsentence-construction

"It's a bit confusing to talk about evolution as a process driven by randomness. In reverse, most of the processes​ we talk about in evolutionary biology can be described in strict mathematical formulas. The best way to think about it is to take them as the results of the probabilities of the actions on nature."

Which phrase can i replace the "in reverse" in the text to indicate that the reality is the opposite than the common belief holds.

Best Answer

Your first sentence is confusing. I think you mean to say that it's misleading to talk about evolution as purely driven by randomness. If you then follow up with any of these, the change in direction makes more sense:

Actually, most of the processes ...

In actuality, most of the processes ...

The truth is, most of the processes ...

It would be more accurate to say that most of the processes ...

The reality is, most of the processes ...

as well as various other expressions. Depending on your audience, you can even get a little creative, for example playing off your use of "driven" to use some automobile metaphors:

Superficially, when we think of evolution, we imagine it driven purely by randomness and chance. However, when we take a look under the hood we find that the engine driving evolution runs on a strict, well-defined set of mathematical formulas.
