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?
Most varieties of hibiscus do not have thorns. However, gardeners have reported finding thorns on certain kinds of hibiscus bushes.
Evolution and miracles are they opposite?
This is a touchy subject. While many believe that belief in God and belief in evolution conflict with each other, that is not necessarily the case. For one, evolution is a proven fact of existence. Everything evolves, or changes, over time. The questionable part is the explanation of that phenomenon. The most common and widely accepted explanation is the theory of natural selection, which most people simply see as evolutionary theory. This well-tested theory does NOT rule-out the existence of God. Many believe that God created the world, and that natural selection and evolution simply give greater insight into how it all may have happened.
What kind of adaptation are thorns?
Thorns are a defensive adaptation of plants against being eaten by grazing animals.
What is the explanation for the evolution of the multicellular organisms?
cell differentiation
Who is associated with evolution?
Charles Robert Darwin, though evolution was already known. Darwin came up with an explanation for evolution. Called the theory of evolution by natural selection.

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 did Lamarck propose a scientific explanation for and why?
Lamarck proposed a scientific explanation for evolution because organisms evovled through the inherititance of acquired charactaristics.
Is evolution the scientific belief?
Yes, evolutionary theory is the scientific explanation for life's diversity.
Why is evolution important in explaining the diversity in life?
Because there is no other testable explanation available for it.
Why is Lamark not called the father of Evolution?
Because it was Darwin who made it a scientifically plausible explanation, by providing a mechanism by which evolution could occur....Natural Selection.

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.
What is an explanation of why bird wings and reptile forelegs are evidence of evolution?
Homologous structures indicate a common ancestor
What is the key word for a well tested explanation for a wide range of observations?
A well tested explanation of a wide range of observations is known as a Theory, such as the Theory of Gravity or the Theory of Evolution.
Responding to someone that states he or she does not believe in biological evolution because it is a theory?
The best way to respond to this is to explain that there is the fact of evolution and the theory of evolution. Evolution is defined as genetic change within a population. This is an easily observable fact both in nature and the laboratory. The theory of evolution is an explanation for the diversity of life on earth based on the observable facts that evolution does indeed occur. It is exactly the same situation with gravity. Gravity is a fact, an easily observed physical phenomenon. But there is also a Theory of Gravitation, an explanation for the phenomenon itself and how it works. That there is a theory for both evolution and gravity does not mean the facts of evolution and gravity are any less true.
