theorie von darwin

Answer

Charles Darwin's theory is known as the theory of evolution by natural selection.

Solution

Charles Darwin proposed the theory of evolution by natural selection

The theory is based on several key observations and inferences:

Observation: Individuals in a population vary in their traits

Observation: Traits can be inherited, or passed from parents to offspring

Inference: More offspring are produced than can survive, leading to a struggle for existence

Inference: Individuals with traits that are advantageous for survival and reproduction are more likely to pass on their traits to the next generation

Key Concept

Natural Selection

Explanation

Natural selection is the process by which organisms with advantageous traits are more likely to survive and reproduce, leading to the accumulation of these traits in the population over generations.

theorie von lamarck in german

Answer

Jean-Baptiste Lamarck proposed an early theory of evolution based on two main principles.

Solution

Lamarck's theory is based on the principle of use and disuse: organisms can develop new characteristics based on their needs, and these characteristics can then be passed on to their offspring

The second principle is the inheritance of acquired characteristics: traits that are developed during an organism's lifetime can be inherited by its offspring

Key Concept

Lamarck's theory of evolution

Explanation

Lamarck's theory suggests that evolution occurs through the use and disuse of characteristics and the inheritance of acquired traits, which is not supported by modern genetics.
