The claim is not supported because it confuses two different genes. The ovarian cancer “gip2” literature refers to GNAI2, not the human GIP gene that encodes an incretin hormone. Studies about incretin drugs or indirect pathway effects also do not show that GIP itself functions as an oncogene in ovarian tumors.
“In adults under typical conditions, the human brain accounts for about 2% of total body weight but consumes about 20% to 25% of the body's glucose or energy.”
The core claim matches standard physiology references: an adult human brain is about 2% of body weight and uses roughly 20% of the body’s energy, with some sources placing glucose use near 20–25% at rest. The caveat is that these figures are usually stated for resting metabolism, and “glucose” and “energy” are related but not identical measures.
“More than 3,000 human genes show sex-specific expression patterns in the human brain.”
Recent high-quality research directly supports the 3,000+ figure: a 2025 single-cell study of the human cerebral cortex reports "over 3,000 unique genes" with sex-biased expression, and independent transcriptomic analyses corroborate counts in this range. However, the claim's unqualified framing omits important context — the number varies substantially by developmental stage (dropping to roughly 1,000 in the adult forebrain), brain region, and methodology, and cross-study consensus on which specific genes are sex-biased remains limited.
“The human brain uses 20% of the body's total oxygen supply.”
The claim is well-supported by multiple peer-reviewed biomedical studies confirming that the adult human brain consumes approximately 20% of the body's total oxygen at rest. This is a widely accepted figure in neuroscience. Minor caveats: the figure applies specifically to adults in a resting/basal state, some sources cite a 15–20% range, and the proportion is significantly higher in young children. These are standard qualifications that don't undermine the claim's core accuracy.
“The Tyrannosaurus Rex lived closer in time to modern humans than to the Stegosaurus.”
This claim is true and well-established in paleontology. Stegosaurus lived ~150 million years ago, while T. rex lived ~68–66 million years ago — a gap of ~80–84 million years. T. rex went extinct ~66 million years ago, and modern humans appeared ~300,000 years ago — a gap of ~66 million years. Since 66 million years is less than 80–84 million years, T. rex indeed lived closer in time to us than to Stegosaurus. Multiple authoritative sources, including USGS and the Natural History Museum, confirm this.
