Final answer:
Genomic data allows scientists to construct more accurate phylogenetic trees than those based on fossil evidence alone by providing DNA sequencing information and genetic relationships between species.
Step-by-step explanation:
Phylogenetic trees are graphical representations of evolutionary history that can be tested.
The availability of genomic data has indeed allowed scientists to construct more accurate phylogenetic trees than those based on fossil evidence alone. Genomic data provides valuable information about the DNA sequences and genetic relationships between different species. By comparing the DNA sequences of extant and extinct species, scientists can gather evidence to support or refute evolutionary relationships, leading to more precise phylogenetic trees.
For example, DNA sequencing from fossil remains of humans and other species has revealed insights into our relationship with other hominid ancestors as well as other animals. In addition, computer programs can analyze DNA sequencing, morphological, and molecular information to determine relatedness and aid in phylogeny construction.
