Describe how Jean Baptiste de Lamarck would have explained the evolution of long roots in plants.

Explain the impact of Mendel's laws of heredity on Lamarck's hypothesis.



Answer :

Final answer:

Lamark would explain long roots in plants through acquired characteristics while Mendel's laws of heredity contradicted this concept.


Explanation:

Jean Baptiste de Lamark would have explained the evolution of long roots in plants through his theory of inheritance of acquired characteristics. According to Lamark, plants develop longer roots over time in response to the environmental need for water. This adaptation to the environment is passed on to future generations, leading to the evolution of long roots in plants.

The impact of Mendel's laws of heredity on Lamark's hypothesis is that Mendel's laws provided a more accurate explanation for how traits are inherited. Mendel's laws, focusing on genetic inheritance through discrete units called genes, contradicted Lamark's idea of acquired characteristics being passed down. This refutation of Lamark's theory by the laws of heredity contributed to the shift in understanding evolution through genetic mechanisms rather than acquired traits.
