Did Venus once resemble Earth?

A recent study suggests that Venus may have exhibited plate tectonics in its early years, similar to Earth. This could have made Venus more Earth-like and potentially habitable. Researchers analyzed nitrogen in Venus' atmosphere as a diagnostic tool to understand its tectonic history. Computer simulations indicated a combination of stagnant lid and plate tectonics models for Venus. However, these findings are suggestive and not conclusive, and upcoming spacecraft missions will provide more insights into Venus' geological past.
