When do you say that a creature has evolved so much that it is no longer the same species?

Animals are considered different species when they can no longer mate to produce fertile offspring.

When a creature undergoes significant changes in its genetic makeup and physical characteristics that prevent it from successfully reproducing with individuals of its ancestral population, it can be considered a different species. Reproductive isolation is a fundamental principle in defining species, meaning that if two populations can no longer interbreed and produce fertile offspring, they are considered separate species.

What According to the theory of today's organisms evolved from past organisms?
No, that isn't a statement made about evolution. The theory of evolution concerns how organisms have changed over periods of time. Everything has to have come from something! However, all living organisms alive today have evolved from predecessors, or have not really evolved much at all, e.g. Gingko bilboa and several species of sea animals.
How do species remain distinct from one another?
Once species have truly become distinct, members of the two species are no longer able to successfully breed with each other and produce fully viable offspring. This may be as little as a physical separation that prevents contact (e.g. new mountain ranges, isolation on islands), to changes in pheromones that individuals produce so that individuals of the two species are no longer attracted cross species even if they encounter each other, to as much as the development of complete genetic incompatibility (e.g. different numbers of chromosomes in the two species).
Why Godzilla is called a hermaphrodite?
Most godzilla myths speak of the creature as being one of a kind or very rare. If there is only one of a species is goes without saying that it would be hard for the animal to reproduce. The typical explanation of their reproduction is they are in fact hermaphrodites. A hermaphrodite is an animal with both male and female reproductive parts. It has no need for a mate at all it has all the utilities to breed with itself. It can produce an egg then fertilize that same egg all by itself. Making it much easier to reproduce if it is a rare creature that doesn't often see others of its species.

How did Darwin's observations on the sharing of species suggest that species have evolved?
Darwin observed that primate like animals that looked vaguely like us, evolved over time to stand upright, evolve large brains, and advanced vocalization through saying how if an early primate had these adaptions, would look much like we all do today.
What animals were on earth when man evolved?
Mostly the same types of animals that we have now, or their immediate predecessors. Humans are a relatively young species; not much has changed since we arrived.
Why do you think Homo Sapiens replaced all other Homo species around the world even though they emerged much later?
yes the homo-sapiens were much better adapted to life on earth and evolved much faster then all other homo species.*read Charles Darwin theory of evoloution.
