Most species that exist in competition with others for resources are all "living examples of evolution," since they're continuing to evolve. If you're looking for a creature that's halfway between two existing classes or families--such as a bird that's "turning into" a lizard, as you suggest--then I don't think you have a clear understanding of what evolution is, or how it works. Evolution is a change in genetics from one generation to another (mutation). Those changes accumulate depending on their effect on survival and reproduction (natural selection), eventually resulting in divergent genetic lines that wind up as different species. As more changes accumulate, differences can widen, moving the species even farther apart in size, appearance, appendages, specific organs, etc. To see observed instances of species divergence (or species 'creation', depending on your perspective), check out http://www.talkorigins.org/faqs/faq-speciation.html. I think that a good example of what your looking for may be found in the salamders and lung-fish. A lung-fish is a fish that has lung with which I can breath air. The hell-diver is a salamander with gills.
As far as we know, there is no bird living without feathers.
The theory of evolution is that all living things come from other living things.
All of the animals currently living on Earth that have feathers are birds, and all birds have feathers. There are fossil indications that at least some dinosaurs had feathers when they were young.
The characteristic of living things most associated with evolution is physical change. According to the theory of evolution, as living things evolve, they experience a number of physical changes to adapt to their environment.
Evolution happens to all living things, all the time.
Feathers are not biotic. For them to be biotic they need to meet all the requirements. Feathers don't need water or food. They also don't contain living cells. Are feathers alive? No, feathers are dead tissue. epidermis, its outer skin layer. As it's produced in the follicle keratin is extruded out, enlarging the feather. This also shows how it is abiotic.
Yes, as in the only living animals, they are. However, feathered dinosaurs, the ancestor of birds, also had feathers.
metamorphisis or evolution. evolution is the period of time in which a living organism slowly changes.
Evolution needs a living organism to start, so, about 3.5 billion years ago.
Yes , because feathers are non-living.
It is the idea that living things adapt to their surroundings. Also, the theory of evolution states that all living beings evolved from single-cell organisms
By it's definition. Evolution is the change in allele frequency over time in a population of organisms. All living things evolve by this definition.
The theory of evolution is states all life evolved from a single living cell.
Evolution is the one that can best describe the development of living things.
We classify living things to keep track of the branching evolution of each living thing.
The answer lies in their DNA, but the simplest way to tell that hummingbirds are truly birds is that they have feathers, and the only living creatures with feathers are birds.
No, for instance plants are living and they do not move.
You may be living close to a birds nest.
