Mainly that animals can change their own forms over time and that these traits are inherited by their offspring. A classic example is of a giraffe making its neck longer and longer by stretching for food that is high in the trees. These individuals would then produce children with long necks.
This concept of evolution is incorrect because individuals do not have conscious control over physiological changes to their body structure, and these conscious changes would definitely not be inheritable by offspring. Change is caused by random mutation in genes. Changes in body structure only happen at the group level because individuals born with an advantageous trait will produce more children than those who don't.
However, it should be noted that the newly emerging field of Epigenetics shows that Lamarck was at least partly right. The environment in which an individual lives can determine when or if a gene is activated. This can be passed on to offspring.

natural selection and common descent
Yes, the evidence from systematics, paleontology, botany and field biology plus the findings of the founders of population genetics.
There is loads you can do about animals, for example; Evolution. Animal behavior. Stem cell research
horses and zebras are similar.They have common ancestors.
Lamarck proposed the idea of "inheritance of acquired characteristics," suggesting that organisms can pass on traits acquired during their lifetime to their offspring. He believed that these acquired traits could lead to evolutionary change over time. However, his ideas have largely been discredited in favor of Darwin's theory of natural selection as the primary mechanism of evolution.
Scientific theory
Adaptation, natural selection, genetic variation, and speciation are key concepts that describe and influence the theory of evolution. These ideas explain how species change over time in response to their environment, leading to the diversity of life we observe today.

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.
No. There is no real evidence about that
