When looking at the fossil record, similarities in anatomical structures can be seen. what is the term for the common ancestry?

Macroevolution. It is an evolution that is viewed above the level of species. This can be used to assess the diversity of the entire clade and the position to the tree. It encompasses the grandest trends and the transformation in the evolution. This can be done by by reconstructing the natural history of life using the evidences that can be found such as geology, fossils, and compared it to current living organisms. This can only be seen when we look on the large scale of life history.

Proteins are the workhorses of the cell, controlling virtually every reaction within as well as providing structure and serving as signals to other cells. proteins are long chains of  amino acids  , and the exact sequence of the amino acids determines the final structure and function of the protein. instructions for that sequence are encoded in  genes  . to make a particular protein, a messenger ribonucleic acid (mrna) copy is made from the gene (in the process called  transcription  ), and the mrna is transported to the  ribosome  . protein synthesis, also called  translation  , begins when the two ribosomal subunits link onto the mrna. this step, called initiation, is followed by elongation, in which successive amino acids are added to the growing chain, brought in by transfer rnas (trnas). in this step, the ribosome reads the  nucleotides  of mrna three by three, in units called  codons  , and matches each to three nucleotides on the trna, called the anticodon. finally, during termination, the ribosome unbinds from the mrna, and the  amino acid  chain goes on to be processed and folded to make the final, functional protein
