Daniel Trevizo Bis2A F03 994781367 12/3/09 Synopsis 10 Most researches say a species is a gene pool with a set of populations that can reproduce with one another and that are unable to mate successfully with other populations. If we were to find an assemblage of small multi-cellular organisms of several distinct types what type of spe- cies would we classify them if they reproduced sexually and asexually? It would be difficult to classify these unknown small multi-cellular organisms to one of Zimmer’s definition of species. The organisms are found in a small amount meaning that they had to be isolated on there own to create there own gene pool and mate with one another. This would classify the organisms as a biological species were members of a population can mate with one another and with other popu- lations in the same species, but not with individuals of other species. The fault in this logic is that the cellular organisms can reproduce sexually and asexually as well, meaning that they do not

Unformatted text preview: need to mate with one another half the time. Then we could readily say that the organisms don’t have to mate to keep reproducing half the time and we are lead to the conclusion of a phylogen-etic species concept. The phylogenetic species concept excludes the idea of sex and states that all species descent from a common ancestor. To propose this idea for the multi-cellular organisms we would have to study there evolutionary history, measure there gene flow between populations and characterize the organism ecological role. Since the organisms were found in a small as-semblage I believe they can be classified under a biological species concept. The organisms were isolated for so long and had to mate with each other or asexually reproduce but a consistent set of genes stuck around with these organisms classifying them as there own species....
