The study looked at how different traits in a plant called Impatiens capensis affect its survival and reproduction. They found that traits like seed weight, germination date, and plant size directly or indirectly influence the plant's fitness. This shows that there is a type of natural selection happening, where certain traits make the plant more likely to survive and reproduce. The researchers didn't find evidence of stabilizing or disruptive selection, meaning the plant's traits are not being pushed towards an average or extreme value. Overall, the study suggests that early events in a plant's life can have a big impact on its overall fitness, even though there may not be much genetic variation for these traits to change over time.
