  1. Re:Evolution is not an Observed Phenomenon on Belief In Evolution Doesn't Measure Science Literacy · · Score: 1

    There's a lot of misinformation and misconceptions about how animals are related. Dimetrodon, a reptile that lived almost 300 million years ago is more closely related to mammals than any other extant group. "Reptile" is an awful catch-all term that includes lots of species not even closely related to each other. Crocodiles are much more closely related to birds and dinosaurs than they are to other reptiles, for example.

    gentle acceleration because that is not only fuel-efficient

    Citation needed.

    Over a 50 mile stretch of road, the car accelerating at 1mph/mile will use more fuel than the car accelerating quickly up to 50mph. That is taken to the extreme, but it illustrates the point that more gentle acceleration does not necessarily mean better mpg - there must be a sweet spot in the middle somewhere, and I personally would guess it's a bit quicker than most would guess (my personally opinion is foot flat to the floor at low revs).

    I'm a hypermiler. I get 51 mpg out of my diesel minivan, But I have to work really hard at it, drive slowly, draft trucks, avoid braking, coast and engine-brake whenever I can.

    Engine braking is just as bad for fuel efficiency as ordinary braking is. The reason it's recommended is to preserve brake pads (and prevent brake overheating in extreme cases, like trucks down long hills), not to increase mpg.

    When you say engine braking, I assume you mean deliberately changing down one or two gears to increase engine braking, rather than using the gear you were in. Taking the car entirely out of gear (or dropping the clutch) when braking is obviously bad for mpg because the car uses fuel to maintain tickover as you are braking, not to mention the additional strain put on the brakes.

    Note : this is true for (most) modern cars with fuel injectors, which will not use any fuel when in gear with no accelerator pedal application. Older cars with carburetors will use fuel depending on their revs even with no accelerator pedal application. So, for optimum mpg for older cars, it probably is best to coast in neutral at tickover down hills just using the brakes. However, this is not very good for the brakes. You could turn the engine off altogether down long hills in old cars for even better mpg.... this is most definitely extremely not recommended, for lots of reasons.

    You want the rule : it's first to name, and that's basically it.

    If you want to go around calling a dinosaur "scrotum humanum", feel free, but everyone will think you strange.

    It definitely breaks the rules in terms of nomenclature, but scientific naming changes all the time anyway, redefining species into other places, etc.

    My personal pet peeve is "Reptile". That contains every land vertebrate that was not a bird, mammal, dinosaur or amphibian. What people don't mention is that mammals evolved from separate reptiles to everything else, and we're more closely related to dimetrodon than birds or dinosaurs are or were. "Reptile" is just a crap catch all term that doesn't mean anything.

    What I meant by "good cause" was that hunting generally is much easier with things we can easily hunt. Getting rid of stuff that can easily kill us is a good thing, even if it is difficult. Humanity also drove off loads of large carnivores, not to eat obviously.

    There's also no reason not to think that a large part of the effect of humans on the megafauna was by killing the young.

    I agree, and that could be the predominant means of humanity wiping out things like mammoths. However, there's no evidence for it. There is evidence for people killing adult mammoths.

    And what is the mantra to chant when you hear the word "correlation"? All together now : "correlations are not, of themselves, evidence for causation."

    Correlation _is_ causation a lot of the time. That mantra you chant is wrong. Correlation shows something going on that is connected between the two things. It may be caused by other things, but they _are_ connected in some way, otherwise there would not be any correlation.

    This particular creature is alleged over 60 feet tall, and more than 10 times the height of a man, which makes it more than 1000 times the mass of a human.

    Well.... no. If we take human height to be 2m and weight to be 100kg (This is me, by the way, I've just used these numbers for simplicity) :

    Elephant = 4 metres or so, 2 * height, therefore should weigh 800kg. Actually, they weigh about 7000kg.

    Giraffe = 6 metres or so, 3 * height, therefore should weigh 2700kg. Actually, they weigh about 1200kg.

    The early estimates of this dinosaur's weight are about 77000kg, so not too far off your estimate. Most of its height is in its long neck.

    People have been claiming that giant sauropods must have been semi-aquatic (or fully aquatic) because of their huge size for centuries, and this was the prevailing paradigm until the last 50 years or so. There's quite a lot of evidence now showing that they were at least mainly terrestrial.

    As to how big they could get... simple mechanical engineering was the cause of the now mainly discredited aquatic theories, I think you'll probably have to find someone who actually knows a little about it.

    Amontons' First Law: The force of friction is directly proportional to the applied load.

    Therefore, in a perfect world, it doesn't matter at all how heavy your car is, it should go around corners at the same speed all other things being equal. However, it's (obviously) more complicated than that. Generally the lighter your car, the better it will go around a corner. This is mainly due to the way the tyre interacts with the road, and the way it deforms under load.

    The first automatic I ever drove was an 18 tonne truck. I got in, and was just confused for a second. I then went and asked my boss how to drive it.

    I'm glad I had that experience, though, because temping as an HGV driver you often turn up to places with a keycode to get in, directions, and not much else (including no one there). No one ever checked what kind of trucks I'd driven before, I'd only driven Mercedes manuals up until that point. My first experience with a semi-auto full size artic truck was at 4am in the morning with no one about. This semi-auto used a clutch pedal to get started, then switched to full auto when moving - the trouble was remembering to drop the clutch when you're stopping (often hours after you last used it). It was relatively intuitive, though.

    The EU is actually much more liberal than just about everywhere else in the world in regards to raw milk. It's actually illegal to sell something called Roquefort made with pasteurized milk (you can make it, just not call it Roquefort).

    Brazil has a lot of diversity but being 50 percent white means being 50 percent being something else.

    That remaining 50% is lots of other things, mainly black, brown (this is closer to how it is described in Brazil, although not politically correct in the US), indigenous, middle eastern, east Asian, and others. The US, by contrast, is almost 3/4 white.

    Do they have as many Russians? As many people from the middle east?

    In my original post I mentioned Brazil has more people of Lebanese descent than Lebanon, they also have a large Syrian population. I don't know the Russian population of Brazil, but they do have relatively large populations of other east European peoples, such as Ukranian and Polish.

    As many Muslims? Do they have large Buddhist communities? Do they have Amish?

    You probably don't want to conflate religious diversity with racial diversity, they're not the same thing.

    Brazil is _slightly_ less religiously diverse than the US, I admit. About 75% of Americans are Christian, whereas about 86% are Christian in Brazil. In the US Islam is at 0.6%, Buddhism is at 0.7%, Hinduism is at 0.4%. Contrast this to somewhere like England : Christianity 59%, Islam 5%, Hinduism 1.5%, Buddhism 0.5% (and 0.7% Jedi). This shows that England is much more religiously diverse than the United States.

    How many distinct Indian tribes do they have? I doubt more then four or five. We have that many in some states.

    You're really beginning to show your ignorance. I'll start you off with this. That list does not include many original tribes that have been integrated into the main Brazilian population (like American Indian tribes have been in the US).
