If we follow the real hierarchical taxonomic system, which statement would most likely be correct? Fartblings cannot possibly be in a phylum AND in a kingdom there would be the same number of creatures in the kingdom and the phylum there would be more creatures in the phylum Fartata than in the kingdom Bedazla O there would be fewer creatures in the phylum Fartata than in the kingdom Bedazla
- Select the reason why is the morphospecies concept problematic for scientists,1. All of the above2. This concept allows scientists to define too many species because it is entirely subjective3. You can get cryptic species that look too similar to identify4. Genetic information might reveal that there are more or fewer species than what the morphology of the organisms impliesActivity 3.

What characteristics do primates and rodents have in common? 2. Which Rodents? of animals are birds more closely related to? Reptiles or group 3. What do amphibians, reptiles, birds, rodents, and primates have in common? 4. What characteristic is unique only to birds and reptiles? 5. Fish and primates have a common ancestor. What characteristic does this ancestor have?TRUE OR FALSE 1. The science of cladistics produces a system for naming and classifying organisms. 2. The broadest categories in the system of classification, bellow kingdom level, are called phyla. 3. The only taxonomic unit that is needed to be written in entirely lower case letters are the genus level. 4. When all the organisms in one taxon comes from a single common ancestor, the taxon is considered to be monophyletic. 5. The presence of opposable thumbs in humans and other apes means that we share a common ancestor; this character shows homology. 6. When a derived character is shared by members of the clade, the process is called a symplesiomorphy. 7. Sexually and asexually reproducing organisms which includes polyphyletic groups are known as the phylogenetic species concept. 8. Sympatric speciation occurs when the formations of new species happen in the same geographic area. 9. When a tree is unrooted, it is not necessary needed to have an outgroup. 10. Derived characters are…

C R The figure shows the phylogeny of seven species of beetles (A-G) and whether the beetles have (?) or do not have (x×) one of three stripes. It also indicates the color of the beetle (R for red and G for green). Based on the phylogenetic tree and the principle of parsimony, the absence of stripe in species is most likely O 1; E and F; an evolutionary reversal O 2; E and F; due to convergent evolution O 2; E and F; a synapomorphy O 1; E and F; a synapomorphy O 1; E andF; due to convergent evolutionA.
