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 are the 5 major problems with the Big Bang theory?
The five major problems with the Big Bang theory are: 1) The horizon problem, 2) The flatness problem, 3) The magnetic monopole problem, 4) The dark matter problem, and 5) The dark energy problem.
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.
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.
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.
How many major keys are there in music theory?
There are 12 major keys in music theory.
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.
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
How many major key signatures are there in music theory?
There are 15 major key signatures in music theory.
What is the major problem with the theory of biogenesis?
Biogenesis? You mean, abiogenesis? There is no theory of abiogenesis yet. Some people have done spurious calculations using information theory. I consider these efforts a problem, in that they detract from serious consideration of abiogenesis. The problem is that cells are hideously complex, and the gulf between self replicating cells and amino acids (which form naturally in a wide range of environments) is very large. One hypothesis for bridging this gap is known as the RNA world hypothesis, but there is as yet no decent general theory of abiogenesis.
