Darwin based his theory on things he saw. For example he noticed how farmers bred animals for different characteristics. Darwin also observed variations among birds and thought that this was a result of natural selection enabling some birds better survival chances that others.
However Darwin's theory is deeply flawed because these changes can never result in new species being developed.
Darwin said if it could be shown that complex things did not develop from simple things then his theory would not stand.
Scientists know these days about the complex biological machines that are found inside cells and these cannot be reduced to simpler forms
Phylogenetic classification is based on evolutionary history and relationships among organisms. It organizes species into groups based on shared ancestry and evolutionary relationships, using information from genetic and morphological similarities. This approach helps to study the evolutionary development and relationships among different species.
Evolutionary classification groups organisms based on their evolutionary relationships and ancestral history, while traditional classification focuses on similarities in observable characteristics. Evolutionary classification aims to reflect the evolutionary history of organisms, while traditional classification is based on shared physical characteristics. As a result, evolutionary classification can provide a more accurate depiction of the genetic relatedness among species.
The term is "phylogeny," which is the study of the evolutionary relationships among organisms based on similarities and differences in their genetic and physical characteristics.
It showed that different-looking animals are actually related. It showed new evolutionary relationships between animals. it changed ideas about which animals were closely related
Yes, in evolutionary taxonomy, the classification of organisms is based on their evolutionary relationships and history rather than any preconceived plan, purpose, or design. It takes into account the evolutionary process of descent with modification through natural selection.

Through the evolutionary biology which attempts to explain events and processes that have already taken place.
The ideas of descent with modification are based on fossils and the modern organisms he found basically says that genetic changes are inherited by later generations.
The procedure of grouping organisms based on their evolutionary history is called evolutionary classification. It is also called Darwinian classification.
They thought the evolution of new species is linked to environmental changes
