Because scientist found another criteria for classifying organisms such as their DNA composition
Evidences that Taxonomy uses to group or categorizes species range from <span><span> 1. </span>"Fossil Records</span> <span><span> 2. </span>Comparative anatomy</span> <span><span> 3. </span>Comparative embryology</span> 4. Biochemical information <span><span> 5. </span>Cellular structure</span> <span><span> 6. </span>Behavior</span>" <span>We also suggest that taxonomy has played various roles mainly in many aspects in Zoology, Botany, Anatomy and Physiology –aspects that include animal and human structures and functions. As the biotic community is so diverse it is classified to Biodiversity and the existence of properly assorting by set standard. </span>
The <u>nuclear envelope</u> is composed of two concentric lipid bilayer membranes separated by an intermembrane space of about 20-40 nm. The outer membrane is continuous in many places with the rough endoplasmic reticulum. Like the rough ER the outer membrane of the nuclear envelope is dotted with ribosomes.
