Question

Mention the tools for tracing evolutionary relationship

Answer 1

Tracing of evolutionary relationship is a vast process, carried out among all organisms present on the earth not among citizens.

• Homologous organs have same basic structural design and developmental origin but different function. They have been inherited in some way from common ancestor. These organs helps in understanding the path of evolution that how from a common ancestor they have evolved with a different function. They give the evidence of divergent evolution that from a common ancestor these structures diverge to different function during the course of evolution. Analogous organs are the examples of convergent evolution.
• Evolutionary relationship can also be determined by study of fossil fuels.
• Evolutionary relationships can be traced by comparing the genetic sequences of the organisms, there are various software's available which can draw a phylogenetic tree. A few examples of these softwares are PHYLIP, Clustal W etc.
