The Origin of Metamorphosis
Metamorphosis is a natural process that changes an animal from one form to another. Some species go through the entire process, while others only undergo partial metamorphosis. A salamander's metamorphosis includes a loss of its tail fin and internal gills, as well as a change in its skin structure. In anurans, metamorphosis involves modifications to nearly every organ in the body. Tadpoles lose their horny teeth and internal gills, and dermoid gland morphogenesis is evident in their limb development. Insects with complete metamorphosis have an advantage over other species that do not.
The process of metamorphosis is associated with a change in the form that provides adaptation to the environment. A butterfly, for example, begins as a larva crawling across the ground and feeding on leaves. In contrast, an amphibian larva develops into a swimmable tadpole, which uses gills to breathe, and later absorbs its tail to form its legs.
In amphibians, the hormone thyroxin is a key factor in metamorphosis. Thyroxin stimulates metamorphosis, while prolactin inhibits it. Scientists can study the effects of hormones on the metamorphosis by artificially administering hormones to animals during their pre-metamorphic stage. However, these hormones can have negative effects on the animals. Although scientists are unsure of the origins of metamorphosis, they do know that without the process, animals would die.
Although the origin of metamorphosis remains a mystery, scientists are beginning to understand the basic biology of this life process. For example, some research is aimed at unraveling the mechanisms that control this process in humans.
The Artist's Heart Podcast
"The Artist's Heart" a new tell-all podcast about creating art, selling art, and the power of Creativity to heal.
In this new podcast “The Artist’s Heart, Conversations with Joe Semprini” Joe talks with guest artists about the power of creativity and creating art from the heart to heal from his own Cancer, and bring joy to the lives of art lovers.
Joseph Semprini has been an artist all his life and rode the wave to Hollywood and the west coast celebrity art scene with all the excitement of the seventies and eighties and then never stopped. He did, over time, move from Shirley Temple’s former mansion to a more modest studio in Newport Beach, California.
About Joe Semprini
“I taught school for seven years in Connecticut. And then I said, you know, it’s time to move in grow. And I just actually packed up my car and left. And I landed in Santa Barbara, which was a beautiful area. And I started showing in San Francisco and then I go back to Connecticut make the sculptures or paintings and ship them out to the West Coast or, and do some shows in New York or Boston and then but I was showing her all these galleries on the West Coast and kind of you know, got addicted to the California lifestyle.”
“I never thought I’d be welding up things. When you weld up something and t gets suspended in the air…. It’s just really mind-blowing There’s something about the welding that its hot metal burning. It’s like the core of the Earth coming through the welder as so it’s got this electric feeling for sure..The way they land, the way you set them. It just blows your mind.”
“I’m a seven-year cancer survivor. And you know, you go through life and death that was pretty serious, then when you come out of that, you know life is a gift. I want to give portions to charity from the proceeds of the website because I believe art heals people”
