It depends what you mean by that; there
is horizontal gene transfer between organisms, and certain apparently deeply significant events in evolutionary history appear to have occurred by advanced symbiosis - most obviously the history of mitochondria and other organelles in Eukaryotic cells.
But the extent to which these events have influenced evolution is not clear, particularly among the "higher" organisms. Also, it is not clear to me that these are not considered most productively as special forms of individual heritable variation (of which mutation and sexual recombination form the two most important examples) upon which the normal processes of natural selection then operate rather than as distinct processes of evolution.
Finally, various non-adaptive effects certainly do occur (genetic drift and the founder effect to name just two) but, again, these are processes that operate with, rather than instead of, descent with modification.
Even if larval hybridization does turn out to be correct; it will represent a new means of generating genetic variety rather than a strictly alternative means of evolving.
