  • :OP link:- from the American eel (Anguilla rostrata), which slithers between ponds after it rains, to the longspined sea scorpion (Taurulus bubalis), an ornate looking coastal fish that hops out of tide pools when oxygen levels dip too low. And then there’s the Atlantic mudskipper (Periophthalmus barbarous), a fish with bulbous eyes and arm like fins that crawls around on mudflats to find food.

    Mudskippers can be observed climbing out of the water directly, or viewed via numerous video clips on the internet.

    From the comments on amphibious fish: –

    And why have we never observed anything like it?

    Fundamentaists have never observed fish making the transition from sea to land, because their faith-blinkers blank out observations and scientific evidence.
    There is an abundance of evidence but it will never be seen by those who refuse to look for it, or look at it!

    At what point do people give up on the bogus, religion based evolution theory

    They then sit in denial, making laughable claims illustrating their profound ignorance of the evolutionary biology which has been established in reputable scientific studies, thousands of times during the last 150 years!

  • Then there is also this paper: –

    Night-time vision evolved millions of years ago in early mammals, a study suggests.

    The photoreceptors that help us see in dim light developed from colour-detecting cone cells in Jurassic mammals, according to genetic evidence.

    The evolution of night-time vision is regarded as a landmark event in the rise of mammals.

    A nocturnal lifestyle allowed the first of their kind to avoid predatory dinosaurs, say scientists.

    Co-researcher Dr William Ted Allison of the University of Alberta, Canada, said the development of night vision was a “critical step” in the dominance of mammals.

    “We’re learning how mammals evolved their vision to survive at night-time and avoid dinosaurs,” he told the BBC.

    “That’s what allowed mammals to diversify and become abundant in the world.

    “They did that by switching their daytime vision in the cones to allow night-time vision using their rods.”

    Genetic research published in the journal, Developmental Cell, suggests the light-sensitive rod cells in our eyes originally developed from colour-detecting cone cells millions of years ago.

    Early mammals lived alongside dinosaurs hundreds of millions of years ago, adopting a nocturnal lifestyle to avoid being attacked when dinosaurs were active by day.

    It has been a mystery how early mammals evolved the night vision that enabled them to survive and prosper.

    Anand Swaroop of the National Eye Institute, part of the US National Institutes of Health, commented: “The majority of mammals have rod-dominant retinas, but if you look at fish, frogs, or birds, the vast majority are cone-dominated – so the evolutionary question has always been, ‘What happened?'”

    The researchers analysed the genetics of rod and cone cells in mice, zebra fish and other animals.

    They found there was a switch towards a dominance of cones over rods in early mammals.

    “…Early mammals changed one type of cell from capturing UV light – which isn’t necessary at night – to something that is just extremely sensitive to light,” said Dr Swaroop.

    Humans depend more on cones for our vision, but that happened later when our ancestors evolved to take advantage of the daylight hours again.

  • I was wondering how computer languages might evolve to properly exploit the 1000 cpu chip.
    In nearly all languages, loops presume sequential execution. We need a loop where each iteration is presumed to occur in parallel, with means to count and summarise. Files are presumed sequential. They need to be conceptualised and accessible as unordered collections of records. Perhaps computations will be unordered, then sorted for human display at the last second.
