Does "if speculative" mean "if venture/take some risk to speak"?
Context:
The origin of life is a flourishing, if speculative, subject for research. The expertise required for it is chemistry and it is not mine. I watch from the sidelines with engaged curiosity, and I shall not be surprised if, within the next few years, chemists report that they have successfully midwifed a new origin of life in the laboratory. Nevertheless it hasn't happened yet, and it is still possible to maintain that the probability of its happening is, and always was, exceedingly low - although it did happen once!

It means we can only speculate about the origin of life; we were not there when it happened, so we cannot prove our theses scientifically. The subject is therefore a speculative one.
