- Ted, here's some evidence that you may actually want to pay attention to.
-
- 1. Paul Anderson, the champion weightlifter, back-lifted over six thousand
- pounds at Toccoa, Georgia, in 1957. (Source: _Book_of_Lists_) What does
- this do to your calculations?
-
- 2. Your calculations using Kaz show that a 24,000 pound animal that feeds on
- low grade material like grass would collapse under its own weight, since
- even if it were as strong as Kaz it could support only 21,000 pounds, and
- then only for a short time; feeding on grass would make the scenario even
- more implausible. Now the catch: we actually know of a twelve-ton elephant.
- (I can dig up a reference if you want.)
-
- Note to Ted's opponents: though these examples are not as conclusive as
- others that have been posted, I think that they stand a better chance of
- getting Ted's attention. For example, somebody's parody of Ted's post
- using an ant might be dismissed by Ted because ants don't have bones or
- muscles like vertebrates do. Someone else's example of long jumpers and
- sprinters can be dismissed because the issue here is sheer ability to
- support weight. In other words, it seems somewhat reasonable to say, "If
- Kaz couldn't lift this car, then no human being can," even though it is
- not reasonable to say, "If Kaz couldn't jump this far, then no human
- being can."
-
- I do like the reptile muscle example, which Ted seems to have misunderstood.
- As someone else has pointed out, the argument is *not* "reptile muscle can
- be twice as strong as mammalian muscle, therefore sauropod muscle is" but
- rather "some vertebrate muscle is twice as strong as mammalian muscle,
- therefore for all we know sauropod muscle *might* have been twice as strong,
- so there is a gap in Ted's proof." Ted, what do you say to this? Saying
- that there is no way a herbivore could have big muscles is handwaving;
- elephants are herbivores.
