Is it possible for humanoid life to develop on a 1.4 G planet?
I'm writing a JRPG-inspired novel set on a planet with 1.7 Earth masses and 1.4 Gs, but is it possible for life to even develop on such a high-gravity planet in the first place? I tried scouring the internet for concrete answers, but the only helpful source I can find about this is from Artifexian's video about building terrestrial planets. He claims that the upper limit for planets developing life is 3.5 Earth masses and 1.6 Gs, but I'm not entirely sure if that's correct.
IMPORTANT NOTE: This is not about humans moving from Earth to a high-gravity planet. My story will be mainly a fantasy one taking cues from many Japanese RPGs, where life in-general (including human-like species) have already evolved on the planet in the first place. I just like to use some semblance of realism to avoid falling for fantasy-related pitfalls.
