Thorns are a plants systematic defense against predation by herbivores. In plants with this defense there must have been a variant that had a proto-thorn that helped it defend against herbivores and leave more descendants with the thorn trait. ( simplistic explanation, but valid )

Why is Darwin's theory of evolution better than Lamrack's?
Darwin's explanation for the fact of evolution was better than Lamarck's explanation and fit the fact of evolution. Natural selection solved much of the species problem, but acquired characteristics did not have the empirical support and explained nothing in the end.
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Do hibiscus have thorns?

What can you concluded about the theory of evolution from the evidence that you have gathered?
That the theory of evolution by natural selection fits the facts of evolution. The theory of evolution by natural selection is based on myriad lives of converging evidence and is the best explanation we have for the adaptive changes leading to speciation in populations of organisms.
Why was evolution considered a theory?
Evolution is considered a scientific theory because it is a well-supported explanation of how species change over time through natural selection. In science, a theory is an explanation that has been rigorously tested, supported by evidence, and can make accurate predictions about the natural world. Evolution meets these criteria, hence it is considered a solid scientific theory.
