It’s a little cheap to say eagles are the projectile, as they can continuously update their trajectory until the moment they grab their prey. Humans have to get it right right at the moment the projectile leaves their hand; they can’t correct as the projectile flies.
- Retric 5y agoA Peregrine falcon in a 200 MPH dive assuming ~0.05 second reflexes is completely unable to do anything to correct their flight path within the next ~15 feet. Throwing accurately might seem complex, but chimps have been recorded throwing rocks at targets and once the basics are down being slightly better at throwing probably doesn’t add much difficulty.
- xyzzyz 5y agoAnd why exactly would you assume 0.05s reflexes? Why don’t you assume, say, 0.01s instead?
- Retric 5y agoFastest recorded visual reaction time in any animal was 0.015s (15ms) for a tiny fly to sudden bright light. The general rule is it increases with the physical distance a signal needs to travel across an animals nervous system and the complexity of what’s being responded to. So, while I don’t have exact measurements on hand ~50ms is good enough for an internet comment.
- pfdietz 5y agoAccurate human throwing requires a timing accuracy of 1 ms.
- Retric 5y agoPrecision of 1ms not timing of 1ms. It’s just like taking a step you can chose when to start but you need to synchronize motions after that point to maintain an efficient stride. In the end that kind of precision is extremely easy for nervous systems as the lag just gets built in. Which is how hummingbird hearts can do 21 beats per second with different timings between each of the 4 chambers at sub 1ms precision.
