A study on lungfish, bony fish and cartilaginous fish has a great deal to offer in understanding development of legs for life on land. Lungfish are ancient ancestors of tetrapods - four legged animals. Walking on their fins and breathing air, lungfish bravely moved onto the land. Research has relied on bones preserved as fossils, but muscles cannot be "saved" in this way. A fetus shows ancient stages in a creatures development. This is why a human fetus seems to be reptile-like in its early stages. Examining muscle development of modern lungfish is very informative. Tests were also done on cartilaginous fish such as sharks and ordinary fish. Embryos of cartilaginous and bony fish were genetically altered to promote growth of precursor pelvic fins that in lungfish became legs. Engineered cells were made to emit red and green light. The study on muscles highlighted the fact that bony fish evolved legs while cartilaginous fish did not. Pelvic muscles of bony fish are a ...

Australian green tree frogs live in the dry desert without dehydrating. This has been a mystery - until now. They move from a cool night into warm burrows. Then they "mist-up". They sit in the cold air for hours until they can hardly move. There is a good reason for this. It has been discovered that their skin "takes-on" water. Inside the burrows water is in the air due to the warmth. Droplets form on their cold skin by condensation. A group of tree frogs frequented a hollow tree in the dry outback. Researchers caught some frogs, cooled them in the cold night air, lowered them into the log in a cage for a quarter of an hour, Then tested them. The frogs gained 0.4 grams in weight, their bodies glistening with water droplets. It is now believed that lizards and spiders also use this technique to get water. Earlier work in the laboratory indicates this. Just a little water is enough to survive. http://www.adventure--australia.blogspot.com/ http://www.ty...

Australian jewel beetles are sexually attracted to stubby beer bottles. These are small bottles, brown in color, that fit comfortably in the hand. Darryl Gwynne wrote about the phenomenon in a post-doctoral paper. He had noticed the behavior 23 years ago. Ultimately, the opportunity arrived to inform the world. He was awarded the Ig Nobel Prize. Male beetles were observed mounting discarded stubbies. The bottles are the same tone of brown as female jewel beetles. Moreover, they glint in the sun like the wings of females. Mounting the bottles is dangerous. It usually ends in death for male beetles. They are either eaten by ants or are cooked in the hot sun. It is feared that the behavior will lead to a decline in beetle numbers. However, the beetles are still present in high numbers two and half decades after the behavior was first observed. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia ...
