Question

Choose the incorrect statement about phylogenetic system of classification:

• A. Classification based on the evolutionary features of the organisms is known as the phylogenetic system of classification
• B. The theory of evolution was given by Charles Darwin
• C. Evolution is the gradual change in the characteristics experienced by the organisms over successive generations
• D. Fossils play no role in the phylogenetic system of classification

Answer 1

The correct option is D Fossils play no role in the phylogenetic system of classification

Evolution is the gradual change in the characteristics exhibited by the organisms over successive generations. For example, lemon, mandarin, sweet orange and blood orange have a common ancestor. Out of all of these, sweet orange and blood orange are the closest evolutionarily.
The theory of evolution was given by Charles Darwin. Classification based on the evolutionary features of the organisms is known as the phylogenetic system of classification.
Phylogenetic trees are used to represent the evolutionary relationships between organisms. Phylogenetic trees include both living organisms and fossils.
Plant fossils are the remains of very old plants, preserved in rocks. As the common ancestors may or may not be existing nowadays, fossils can be used to link the different species.
