The following chart lists taxonomy classifications for seven organisms. Some have just one classification, while others have a subclassification. Which four classifications best match the classifications of your fossils? Research the classifications if you don’t know their characteristics. Classification Organism 1 Brachiopoda Organism 2 Mollusca, Gastropoda Organism 3 Arthropoda, Trilobita Organism 4 Chordata, Actinopterygii Organism 5 Pteridophyta Organism 6 Nematoda Organism 7 Ascomycota Now complete the following table to explain your reasoning for the classification of your fossils.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.

this is because the evolution of one species is independent of the other species.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
