Disagree. If there is a filter at all then it could easily be that we’ve already passed it. Maybe the filter is the formation of multicellular life, for example. Also, Earth and Mars have exchanged a lot of material. If we find Mars life, it would not at all be surprising to learn it is related to Earth life.

It's hard to imagine that the change from unicellular life to multicellular life is a great filter. Even single cell life has evolved to crazy complexity that blurs the lines between single and multicellular life.

If it's DNA/RNA based, we might actually be able to determine the relationship and whether that's true or not.
