B uster is feeling shy, as usual. Buster is so acutely shy that researchers at the Seattle Aquarium can't tell whether this giant Pacific octopus is a boy or a girl. If Buster is a boy, he'll have a special tentacle (the third to the right, going clockwise, from the front of its mantle) that is both an arm and a dick. And, since the suction cups on octopuses* also function as taste buds, his special tentacle will be an arm and a dick and a tongue—making all octopus sex fisting and intercourse and cunnilingus, simultaneously. The young blonde giving the "feeding demonstration" to a large pack of squirming schoolchildren explains these facts more delicately.
Or to go at it a second way: even "pure" pigments are nearly always dependent on a structure. Vermillion (mercuric sulfide, HgS) is a gorgeous red, and no matter how finely you grind it, it's still red . . . unless you can get the hexagonal HgS crystals to realign themselves into zincblende-cubic HgS crystals.
There are completely transparent glassfrogs: I've seen 2 and got pictures of them on leaves (with clutches of eggs nearby) in Costa Rica.
Scientists in Argentina recently attached a lipstick-size video camera to an imperial cormorant 's back.
Your hands are, roughly speaking, 360 million years old. Before then, they were fins, which your fishy ancestors used to swim through oceans and rivers. Once those fins sprouted digits, they could propel your salamander-like ancestors across dry land. Fast forward 300 million years, and your hands had become fine-tuned for manipulations: your lemur-like ancestors used them to grab leaves and open up fruits. Within the past few million years, your hominin ancestors had fairly human hands, which they used to fashion tools for digging up tubers, butchering carcasses, and laying the groundwork for our global dominance today. We know a fair amount about the transition from fins to hands thanks to the moderately mad obsession of paleontologists, who venture to inhospitable places around the Arctic where the best fossils from that period of our evolution are buried.
Alright, well, usually on scientific matters, I defer to Wikipedia, mostly because it does try to be pretty will cited and get it's facts straight. So if that's what the current research says, I concede.
They aren't addressing external factors, it seems.

Sperm are single-purposed: They're optimized to get to an egg and inseminate it. But that doesn't mean there isn't more to this cell than meets the ovum.
I'm kinda iffy on the connection to the TCP protocol here. I'm not specifically a network engineer, but afaik the packet transfer throttle is just an added bonus to TCP's main advantage over e.g.
My mother, the one, the only, the inimitable, once celebrated St. Patrick's Day by dyeing everything green: milk to drink and spaghetti for dinner. Bright, Kelly green, spaghetti.
Well, just like there a minor and unimportant variations in our hair, facial shapes (noses, eyes, ears, etc.), skin tones, blood types, eye colors, I guess it stands to reason that there might be slight variations in our vocal apparatus.
Ancient oxygen. Researchers believe that ancient archaea, similar in shape to this Halobacteria, used aerobic respiration 2.9 billion years ago to produce an active form of the B6 vitamin (crystalline structure, inset ).
Beware the blue.

When transplanted to the fertile environment of the Hudson, exotic and invasive species from other lands often have few predators and spread rapidly.
