What is mean by allopatric speciation? Provide for examples of some known speciation events that resulted from geographic and then reproductive isolation. Be sure to thoroughly explain the event. Describe a known example of sympatric speciation, how did it happen?
1. Choose a gene, DNA, or RNA protein that is common to all the organisms in a group. (e.g., hemoglobin, cytochrome C). Select the molecular evidence wisely, i.e., DNA or protein sequence. Even though proteins are preferred proof, DNA patterns are great for studying recent evolutions...
What speciation leads to polyploidy?Cell division:Cell division is the process by which cells multiply. There are two main processes of cell division mitosis and meiosis. In mitosis, the cell reproduces identical cells, and in meiosis, the cells subdivide into four compartments with half the ...
Paleontological evidence is needed in addition to molecular trees. If a group is known to have been much more speciose in the past, it strongly indicates that the relict actually remains from a much larger and extinct group. From this criterion comes the famous term “living fossil” coined ...
Infants of these mothers would benefit from microbiota restoration but FMT may not be a safe option. FMT from a universal donor could be a solution, and an intriguing question is whether FMT from a universal donor is as effective as maternal FMT. While there is some evidence to suggest that...

Different factors were proposed as causative agents of TE mobilization in a wide range of organisms: biotic and abiotic stresses, inter- and intraspecific crosses and populational factors. However, there is no clear evidence of the factors capable of inducing TE mobilization in Drosophila, and data...
