YouTube video (Romanian) by Mihail Pautov presenting research that human brain volume decreased by up to ~10% over the last ~25,000 years. The speaker frames this shrinkage not as degeneration but as an adaptive response to long-term climate change: smaller brains and leaner bodies reduce overheating and energetic costs (thermoregulation). The speaker also cites correlations across centuries and millennia between temperature variation and changes in body/brain volume metrics.
