Answer #1

A. prokaryotes are unicellular in organisation, therefore can not be correct answers.
?B. This can not be possible answers as prokaryotes do not have bilateral symmetry.
?C.Correct opt. protista according to whittaker's five kingdom classification is the evolutionary ancestor of plants ,animals and fungi.
?D.1st animal phylum is of sponges and it is asymmetrical therefore not all animals have symmetrical animal.
?E. radial symmetry only occurs in 2nd phylum of animal kingdom therefore not all animals have radial syy=mmetry thus ,this option is also wrong.

Over 20 species of fish have descended from a single common ancestral species. Fossil evidence shows that each of these species evolved when fluctuating water levels totally isolated small sub-populations of the original ancestral species into several different small lakes and prevented interbreeding. Today they are all completely sympatric (all live in the same large lake.) We can identify them all accurately by their morphology. With this evidence, how best can we hypothesize what type of speciation was involved ?...
