Description: So that's how this prehistoric fish helps explain the evolutionary movement of vertebrates from water to land. Over millions of years, that transition led to the spread of all four-limbed animals, called tetrapods, like amphibians, birds, and even the mammals that are our ancestors. There's even another powerful clue

In principle. what is done is to take the nucleus out of a cell with a very fine micro-pipette or needle and introduce it into an egg. That had been done with amphibians a long time ago, and then there was a long pause of many years before people were clever enough to make that work in the sheep.

English Scientist

As with most animal eggs, the early events of amphibian development are largely independent of the environment, and the processes leading to cell differentiation must involve a redistribution and interaction of constituents already present in the fertilized egg.

My first attempts to transplant nuclei in Xenopus were completely unsuccessful, because the Xenopus egg, unlike those of other amphibians, is surrounded by an extremely elastic membrane and jelly layer that make penetration by a micropipette impossible.

We're not just polluting a river and killing a couple of top predator animals; we're eradicating the krill, the necessary algae. We're dismantling the insect and amphibian worlds. We're going for the building blocks.

The choking humidity makes amphibians of us all, in Bombay, breathing water in air; you learn to live with it, and you learn to like it, or you leave.

Humans are amphibians - half spirit and half animal. As spirits they belong to the eternal world, but as animals they inhabit time.

British Writer

Amphibians have a life cycle that includes time on land and in water, usually with a transformation.

Double Life

Amphibians usually breathe through gills in water and lungs on land.

Breathing Changes

Amphibians often have permeable skin that absorbs water and can be sensitive to changes.

Sensitive Skin

In different cultures, amphibians can symbolize transformation, fertility, or luck.

Cultural Symbolism

Amphibian-related often refers to efforts to protect these creatures from threats like habitat loss.

Conservation Efforts

Amphibian vehicles showcase human ingenuity in adapting to multiple terrains.

Innovation Examples

Amphibian vehicles are popular in tourist areas for unique city and water tours.
