Explanation:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
variety of homology is used as evidence to support common ancestry and biological evidence. These lines of evidence include embryological, anatomical, and molecular (DNA and amino acid sequence) homologies. Embryological development can be observed by studying similarities in the formation of embryos.
Therefore, vestigial structures can be considered evidence for evolution, the process by which beneficial heritable traits arise in populations over an extended period of time. The existence of vestigial traits can be attributed to changes in the environment and behavior patterns of the organism in question.
1. Shared ancestry can be proofed by the presence of homologous compositions. These are the structures that look the same in compositions but they contrast in functions.
Analogous arrangements show comparable functions performed by various species through their varying structures and do not evolve from common ancestors.
2. Common lineage can be shown with an indication of biological importance.
The line of proof is physiology, the similarity of embryo developmental stages, homology in the hereditary materials (DNA and amino acids), fossil remains.
3. Vestigial structures are comparable to the structures functionally serving in other species.
They are reduced in some species due to environmental factors and better adaptation methods therefore, they can be considered as evidence for evolution.
