Which of the following is true about phylogenetic trees?
A
They represent evolutionary relationships among species.
B
They can only be constructed using genetic data.
C
They show the chronological order of species appearance.
D
They are based solely on morphological similarities.
Verified step by step guidance1
Understand that phylogenetic trees are diagrams that represent the evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.
Recognize that phylogenetic trees can be constructed using various types of data, including genetic, morphological, and even behavioral data, not just genetic data alone.
Acknowledge that phylogenetic trees do not necessarily show the chronological order of species appearance. They illustrate relationships and common ancestry, but not the exact timeline of evolution.
Note that phylogenetic trees are not based solely on morphological similarities. They can incorporate multiple data sources to provide a more comprehensive view of evolutionary relationships.
Conclude that the statement 'They represent evolutionary relationships among species' is true about phylogenetic trees, as this is their primary purpose.
