True.
Phenetic classifications
Older methods of classification often rely heavily on observable characteristics, which can lead to inaccuracies due to convergent evolution, where unrelated species evolve similar traits. Additionally, these methods typically do not account for genetic relationships, resulting in classifications that may not reflect true evolutionary lineages. This can misrepresent the diversity and connections among organisms, hindering our understanding of biodiversity.
Convergent evolution can lead to quite different organisms evolving similar body structures. This makes it difficult for taxonomists to decide how the organisms should be classified.

Some potential problems in the theory of evolution include gaps in the fossil record, the origin of complex structures like the eye, and understanding the mechanisms driving rapid evolutionary changes. Additionally, determining the exact mechanisms of speciation and the role of epigenetics in evolution are ongoing challenges.
There is no such thing as devolution, it is always evolution taking place, devolution is just a new word that usually spreads a very naive misconception about the evolution of man. About problems, can you please clarify your question? I personally find it incomprehensible.
Organisms may have similar adaptations when they face similar environmental conditions or challenges. Natural selection can drive the evolution of similar traits in different species to help them survive and reproduce in their specific habitats. This convergent evolution allows different organisms to independently develop similar solutions to shared problems.

Their religious ideology does not permit them to consider the genesis myths to be myths. Also they link many social problems, problems in their minds, with evolutionary theory and modern science.
