Megafauna were actually the norm. Just look at the Dinosaurs and Mammoths. So being smaller is a recent change.
Larger animals are more efficient with their calories, expending less energy per pound vs a smaller animal. Large animals also have a better volume to surface ratio, making it easier for them to keep themselves warm.

If this is true, why do feed efficiency graphs look like this? https://ib.bioninja.com.au/options/option-c-ecology-and-conser/c2-communities-and-ecosyste/feed-conversion-ratio.html https://ib.bioninja.com.au/options/option-c-ecology-and-cons...
- Enginerrrd 4y agoThat's a pretty unfair comparison. Cows eat grass. Pigs and chickens are omnivores that can save themselves from the synthesis of a lot of protein building blocks. Fish are cold blooded so they don't waste a big portion of calories that they eat keeping warm. Only the comparison between chickens and pigs is really relevant here.
