Bangiomorpha
Bangiomorpha pubescens is a red alga.[1] It is the first known sexually reproducing organism. A multicellular fossil of Bangiomorpha pubescens was recovered from the Hunting Formation in Somerset Island, Canada that strongly resembles the modern red alga Bangia despite occurring in rocks dating to 1,047 million years ago.[2] This fossil of a type of red algae is the oldest example of an organism belonging to an extant phylum. The fossil includes differentiated reproductive cells that are the oldest evidence of sexual reproduction. Sexual reproduction increased genetic variation, which led to an increased rate of evolution and the diversification of eukaryotes.
