Answer:
Most of the scientists worldwide do not accept this theory.
Explanation:
Lamarck's theory states that acquired traits can be passed on from parents to offspring. This theory can not be sufficiently substantiated by indisputable scientific evidences hence it is not accepted by majority of scientists worldwide.
Since science is empirical and the theory is mostly based on vague speculations rather than concrete evidence, it was long rejected by many biologists.
This theory suggests that all life forms will gradually evolve from simple to complex organisms while the simple organisms gradually disappear. This is not the case.
