Lamarck predicted that changes inherited in the parent's own lifetime would be inherited. This would mean, among other things that:
- A parent mouse has its tail chopped off. It would have tailless offspring.
- A blacksmith with strong muscles (due to his trade) will have stronger offspring than an otherwise identical non-blacksmith.
- Children would inherit any scars their parents had.
None of the three above scenarios are the case, contrary to what Lamarck predicted.

Was lamarcks idea of acquired traits proven or rejected?
rejected.
Who is Charles Darwin and was his contribution to science?
Charles Darwin was a naturalist. His major contribution to science was the Theory of Evolution.
Which of lamarcks ideas was later found to be incorrect?
The idea of acquired characteristics. For instance. The idea that a blacksmith, who would develop enormous muscles due to his trade, could pass these physical attributes on to his children.
Why did Charles Darwin started the theiry of evolution?
To explain the species problem, " that mystery of mysteries " which was the natural history problem of the day. From his observations and experiments Darwin proposed his theory of evolution by natural selection, which provided a mechanism for the observed fact of evolution.
What were the lamarcks two theories of how organisms evolved?
Concepts more than theories. Use and disuse. A anatomical part of an organism would fade away if not constantly used and would enhance itself is used. The giraffe neck as an example of use. Acquired characteristics. Characteristics that one developed over the course of a lifetime could be passed on to progeny. Such as the developed muscles of a blacksmith could be inherited by his children. Naturally, both these concepts were absolutely refuted by the theory of evolution by natural selection.
How is lamarcks theory of evolution different from theory of evolution?
Make me cum daddy~! Make me moan~!
What was the major problem with wegners theory of continental drift?
The main problem with Wegners theory of continental drift was that at the time he proposed it he had no real proof.
What are the differences between Darwin's and lamarcks theory of evolution?
Larmark's theory was based on the idea that organisms inherited characteristics that they had acquired in life - so, if you have a scar your offspring will have scars. Darwin's theory assumed that offspring inherited characteristics from their parents, but they were more likely to survive to breed if there was advantage to those characteristics.
Major theoris of social problem solving?
Some major theories of social problem solving include social learning theory, which emphasizes how individuals learn problem-solving skills through observation and modeling, and cognitive-behavioral theory, which focuses on how thoughts, behaviors, and emotions influence problem-solving processes. Additionally, ecological systems theory highlights the importance of considering how multiple systems (e.g., individual, interpersonal, community) interact to influence social problem-solving outcomes.
How was Darwin's theory of evolution different from lamarcks?
In Darwin's theory, natural selection plays the key role. Organisms vary through random mutations--slight changes from their parents. The environment determines which are most likely to survive. In Lamarck's theory, changes in phenotype are inherited. This is now known to be (largely) incorrect.
Was lamarcks idea of acquired traits proven or rejected?
rejected.
What is the major theory in science?
Some major theories in science include the Big Bang Theory, the theory of Global Warming, and the Theory of Evolution.
Which major developmental theories are stage theories?
The major stage theories are the Psychoanalytic theory, behaviorism theory and Cognitive theory.
What was the problem with the Continental drift theory?
The fundamental problem with Wegner's theory was that he couldn't explain a mechanism for the movement of plates.
What parts of Lamarcks hypotheses have been proved wrong?
Animal behaviors are not inheritable.
Why was Lamarcks theory disproved?
Weismann started an experiment, where he cut off tails on many mice, and let them live like that. When they had offspring, their offspring had tails, proving that traits that are altered during a life-span, don't get passed on to the next generation
What are the three major forces of psychology?
The three major forces of psychology are behaviorism, humanism, and psychoanalysis. Behaviorism focuses on observable behaviors and how they are learned, while humanism emphasizes personal growth and self-actualization. Psychoanalysis explores the unconscious mind and how it influences behavior.
