In addition to the fossil record, what other kinds of evidence reinforce the evolutionary of life? You may want to use your textbook as a reference. Solution In addition to fossil record, application of Molecular Systematics is very much helpful for easy identification of fossilized organism. Molecular systematics involves comparisons of nucleic acids or other molecules to presume the degree of relatedness which can disclose phylogenetic relationships which usually cannot be determined by non-molecular methods like comparative anatomy. For example, molecular systematics helps us to uncover evolutionary relationships between groups and allow us to reconstruct phylogenic trees among groups of present-day organisms for which the fossil record is poor or lacking entirely. For example, the DNA that encodes for ribosomal RNA (rRNA) changes comparatively slowly. Therefore, comparisons of DNA sequences in these genes are valuable for investigating relationships between taxa that diverged hundreds of millions of years ago. Other molecular methods useful for determining phylogeny from fossil record include Nucleic acid sequencing, Genomic fingerprinting (RFLP) and Amino acid sequencing..

Solution
In addition to fossil record, application of Molecular Systematics is very much helpful for easy
identification of fossilized organism. Molecular systematics involves comparisons of nucleic
acids or other molecules to presume the degree of relatedness which can disclose phylogenetic
relationships which usually cannot be determined by non-molecular methods like comparative
anatomy. For example, molecular systematics helps us to uncover evolutionary relationships
between groups and allow us to reconstruct phylogenic trees among groups of present-day
organisms for which the fossil record is poor or lacking entirely. For example, the DNA that
encodes for ribosomal RNA (rRNA) changes comparatively slowly. Therefore, comparisons of
DNA sequences in these genes are valuable for investigating relationships between taxa that
diverged hundreds of millions of years ago. Other molecular methods useful for determining
phylogeny from fossil record include Nucleic acid sequencing, Genomic fingerprinting (RFLP)
and Amino acid sequencing.
