Oscarella Carmela Evolutionary Dead End
The sponges considered to be an evolutionary dead end because they do not need to change in order to catch prey. The Oscarella carmela has six of the seven major animal signaling pathways (Schmitt and Taylor 2009). This shows that the sponge cells are advance as other animal cells. These creatures do not change because of the food source. Water currents provide microorganisms for sponges to consume, and the sponges filter-feed and collect the orginims from the current to gather nutrients (Schmitt and Taylor 2009). Sponges do not need to evolve to gather food in a better way. The sponge is a dead end because the method they develop works perfectly for millions of years, so they are never going to change. If the food source dies out, then the
