What was the major development in vertebrate evolution?
Evolution of paired limbs was one of major developments . Similarly development of jaws , Amnion etc are also major developments .
How does anatomy explain evolution?
It doesn't. Evolution is explained by population genetics, evolutionary theory.
What was Lamarcks theory?
Lamarck's Hypothesis of Evolution(Small note before answer: Lamarck had a hypothesis, not a theory) Lamarck, as well as other naturalists, hypothesized evolution via environmental change before Darwin. However, many failed to account for changes in the fossil record and interactions of the phenotypes of animals on their environment. Despite Lamarck's advances in the field, he is most remembered in history for the incorrect mechanisms of this evolution that he posited.Lamarck's hypothesis of evolution appeared in his Zoological Philosophical Work written in 1809, featuring two mechanisms of evolutionary change: use and disuse and inheritance of acquired characteristics.His evolutionary hypothesis was as follows:Environmental changes generate new needsThese needs determine the use or disuse of some organsSuch organs develop or are diminishedThe acquired characters are hereditary
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 mammals have jaws?
Yes mammals has jaws ,a dog has jaws lions has jaws and they are both mammals.
Why is evolution considered a theory and not a hypothesis or a law?
In science, a hypothesis and a theory differs in that a hypothesis is a conjecture based on empirical observation or theoretical derivation yet unproven or by any experimental work, and that a theory is a hypothesis that has been rigorously tested by many researchers and supported by strong evidence. Evolution is a theory that has been repeatedly tested, supported by overwhelming evidence, and can be used to explain natural phenomenon very well.
What doeshypothesis mean in sicence?
A hypothesis is an idea suggested in order to explain data (information). It's essentially the same as a theory. For example, evolution is a hypothesis that explains why different groups of plants and animals have different similarities. Once a hypothesis has been suggested, you go and collect more data that will either support the hypothesis or contradict it. In the case of evolution, DNA patterns and protein similarities support the hypothesis.
How do you explain in brief the evolution of computer?
explain in brief the evolution of the computer
Is evolution a theory or hypothesis?
Evolution is an observed and observable fact. The theory of evolution by natural selection explains many things about evolution. The theory generates testable hypothesis, as any good theory does. Remember, theory is the highest concept in science.
What is m-m hypothesis?
Hypothesis? Hypothesis is a proposal intended to explain certain facts or observations
Why was the evolution of jaws an important event in vertebrate history?
The evolution of jaws is believed to be used originally for respiratory purposes. However, it is important to the history of vertebrates mainly because it allowed for more efficient eating.
What is a hypothesis that does not explain an observation?
When you are using the scientific method, you would try to imagine a hypothesis which explains an observation, but you might not succeed. A hypothesis that does not explain an observation would be considered a failed hypothesis. You would then need to invent a different hypothesis.
Did your data support your hypothesis?
so you have to put in did it help you explain your hypothesis
What phylum has jaws and skulls that are important in their evolution?
The phylum Chordata has jaws and skulls that are important in their evolution. These features allowed for more efficient feeding and protection, leading to the diversification and success of this phylum in various environments.
The hypothesis that the evolution of different species occurs?
natural selection
What was the hypothesis that was proposed by Darwin?
Darwin invented the theory of evolution
What is life's early evolution know as?
RNA world Hypothesis.
