It would really be impossible for me to tell you, seeing as though I've never met one. And also because we don't really know what's intelligent but they certainly shared similarities to modern humans in behaviour- they found some really complex tools and stuff with them. Well, complex for...you know...

Lifestyle changes can also impact on your weight: for example, consuming lots of caffeine...and even smoking. Smokers find that when they quit they gain a few pounds even though they may not be eating to compensating for smoking- it's just that their metabolism has decreased without the nicotine...s...

Okay so fluctuations in the abiotic environment would pose a challenge to all organisms. As long as this occurs, death is necessary to ensure the survival of all species...right? You know this really one of those fantastic topics that gets you all excited and then you start thinking about it and hav...

Homo floresiensis (spelling) lives! Okay, probably not physically...but in our hearts, atleast...lame attempt at humor. Is that allowed in these forums? Anyway, so they're isolated...? Is that just a lack of genetic diversity or something? Why is there such significant fluctuations in the sizes of m...

Doesn't evolution mean death anyway? There has to be some sort of mechanism for passing useful information on to offspring....

Size of organisms

There may be a really simple answer to this, and admittedly, I haven't read much on Evolution; but what (besides the obvious- genetic factors) determines the size of an organism? What about that island in Flores I think it was? In Indonesia somewhere anyway...it had the strangest sized inhabitants.....

I was studying for a bio exam (Monday- wish me luck!) and I incidentally came across an answer- or according so some professor of microbiology- he said something about the contraction of microfilaments CAUSING the process of cytoplasmic streaming. Thanks everyone!

I'm sorry, I sometimes need to be reminded that I'm not one of those 'above the law'. Rabbits also eat the placenta; which is odd because they're obviously herbivores. Usually. Apparently it increases the chance for the survival of the mother? And therefore the few offspring they raise...I was just ...

Ribosomes

Ribosomes: Can someone please tell me where they are synthesised? They're proteins, right? I know they're involved in protein synthesis, but what composes the initial proteins which allow the synthesis of other proteins to take place? Without ribosomes, how can you make more organelles involved in t...

I might be wrong, but isn't the woody part of a tree lignin or something? Aren't there phloem as well? And there's those lateral things...what are they..? ...dammit. I don't remember the word. But if you were to saw a tree, and you'd see a star shape- it's those lateral vessels...I know xylem is com...
