- New individuals always come from parents: by seeds, birth or eggs. The exception is a one-time abiogenesis at the beginning of life.
- Offspring are quite similar to their parents and slightly different from each other.
- Offspring are always the same species as their parents.
- Individuals can only successfully breed with members of their own species. This is the definition of a species.
The theory of evolution does not ever violate any of these obvious observations. If some creationist tells you for example that the theory of evolution predicts cats should give birth to dogs, or that crocoducks should exist, he is simply lying by creating straw men. Creationists like to confuse things by using the term kind but if you read the bible, it is just a synonym for species. Creationists like to use kind as a vague synonym for clade.~ Roedy (1948-02-04 age:69)
