BIO153H5 Lecture Notes - Lecture 5: Slime Mold, Red Tide, Paraphyly
Document Summary
How can we test the origins of organelles. Paralytic shellfish poising is associated with the alexandrium catenella protists: this malaise can harbour these diseases for generations. Other cells can actually recognize other slime mould that have the gene to reproduce and grow: different types of slime moles connect to other another. A structure like this they start growing out look for food, they have feeding search pattern (tree like) Plasmodia slime mould: connect to look like the larger cities of japan. Monophyletic group if you cut of a branch and the ancestors and its descendant fall out, nothing else (only one stem falls out) the right amount fall out. Paraphyletic group group does not represent phylogenetic relationships: does not include all of the descendants, if you do a snip test then all of the descendants fall off including parts of other groups (more fall out)
