If Venus had Earth-like plate tectonics in its distant past, did it have life too?

New research suggests the solar system's hottest planet, Venus, could have had Earth-like plate tectonics billions of years ago, opening up the possibility that this hellish once hosted life.

I note from the paper cited, https://www.nature.com/articles/s41...A8q9hpwi_ug==&tracking_referrer=www.space.com

"...Our results indicate Venus-type atmospheres may be a more likely consequence of early active lids when compared to stagnant lids. The present state on Venus may result from an early runawayplate-tectonic-like state in which any putative recycling, loss, or sequestration failed to prevent the rapid accumulation of CO2 in the atmosphere, leading to an extreme greenhouse state and Venus today. If Venus was in an early active lid state, there are open questions: did Venus ever harbour life, and can vestiges from this early life-bearing epoch be detectable from the atmosphere? The existence of a thick CO2-rich atmosphere may imply that life never existed,.."

My notes. Always interesting to see how Venus could be a habitable earthlike planet, at least in the early solar system model. There are recent reports of phosphine in the atmosphere of Venus said to be little Venusians living there too Perhaps all of this evolutionary modeling will establish a universal law for abiogenesis in nature .
