What is an interplanetary theory?

An interplanetary theory is a speculative concept or hypothesis that seeks to explain phenomena or patterns observed between planets in a solar system. It may involve studying gravitational interactions, orbital dynamics, or planetary influences on each other's behavior. These theories are often used in astronomy or astrophysics to understand the relationships and movements of different celestial bodies within a solar system.

What is carnivine's evolution?

Carnivine does not have an evolution, although he may in the future...

What did jean baptiste lamarck contribute to science?

Lamarck proposed an hypothesis that had species evolving desired traits and passing them to their offspring. For example, if you were a bodybuilder, your offspring would be born with larger than normal muscles. This hypothesis, while incorrect, was still significant in the history of evolutionary thought.

You do not want to change though you believe in evolution?

I do not ' believe ' in evolution, but I am convinced by the evidence.

The hominid fossil has the same number of bones in its hand as a gorilla. what type of evidence for evolution does this represent?

That evidence is homologous. Shared common ancestry. In this case you could trace this homology back as far as the common ancestor of gorillas and hominid fossils, or as far back as the emergence of all tetrapods.

What evidence does Walton provide of his romantic leanings?

You could find other reasons, but an obvious example is Walton's wonder at the rough beauty of the north.

Why is DNA the weakest evidence of evolution?

Actually, it is the strongest evidence for evolution. Without one fossil we would know from the DNA evidence that evolution has occurred and is occurring. It is in the DNA of organisms that we see the strongest evidence for common ancestry. The products of those genes are sometimes highly conserved down the ages. Ribosomes, the workbenches on which proteins are made, differ hardly at at between you and pets.

Why is it that lamarck's suggestion that organisms arise spontaneously and then become increasingly more complex is not supported by the theory of natural selection?

Because lamarck thought that traits organisms aquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, aquired traits cannot be passed on to offspring, only traits determined by DNA can.

Why is lamarck's theory not supported by the theory of natural selection?

Lamarck thought that traits organisms acquired during their lifetime would be passed on to offspring. He believed that traits were determined by use or disuse. However, acquired traits cannot be passed on to offspring; only traits determined by DNA can

What best describes all sauropod dinosaurs?

I would say one thing is that all sauropods were herbivores.

What is the difference between divergence and speciation?

Divergent speciation refers to the rise of a new species when organisms that can interbreed and reproduce fertile offspring get separated. Separation can be due to geographical barriers like mountains and lakes.

What part of the theory of evolution by natural selection would explain why there are no wild wolves that resemble daschunds?

The relevant concept is that of the ecological niche. The daschund is adapted to the niche of being a pet for humans, and it would be very badly adapted for the niche of being a predator in the wild.

How do you calculate Evolution Index in sales?

EI = (100 + Product Growth %) / (100 + Market Growth %) X 100

Give an example of evolution as a remodeling process?

Whale fins remodeled from the legs of a ground dwelling animal over some millions of years. The bones are of the same construction and number, just overlaid with flippers now.

What evidence would you use to determine whether the evolution of a group was explained best by gradualism?

In earlier times, we might have been limited to fossil evidence. But in recent decades, some excellent genetic tests have been devised to show whether a certain genetic sequence is the result of rapid adaptation.

Humankind has assumed responsibility for its own evolution through?

Social structure? It's culture? Genetic engineering?

The trouble with any of these answers is a basic misunderstanding of what evolution is. Evolution is the change in allele frequency over time in a population of organisms. Humans are not nearly ready to assume any responsibility for this process yet. Perhaps influence it.
