We are told some fish look after their mates

as to

,,,cooperate and support each other while feeding. While such behaviour has been documented for highly social birds and mammals, it has previously been believed to be impossible for fishes.

Cooperation is far more widespread than is expected in Darwinian, 'Survival of The Fittest', thinking:

Indeed, unexpected 'cooperation' is found all the way down to the level of Bacteria communities as well:

Doubting Darwin: Algae Findings Surprise Scientists - April 28, 2014 Excerpt: One of Charles Darwin's hypotheses posits that closely related species will compete for food and other resources more strongly with one another than with distant relatives, because they occupy similar ecological niches. Most biologists long have accepted this to be true. Thus, three researchers were more than a little shaken to find that their experiments on fresh water green algae failed to support Darwin's theory — at least in one case. "It was completely unexpected," says Bradley Cardinale, associate professor in the University of Michigan's school of natural resources & environment. "When we saw the results, we said 'this can't be."' We sat there banging our heads against the wall. Darwin's hypothesis has been with us for so long, how can it not be right?" The researchers ,,,— were so uncomfortable with their results that they spent the next several months trying to disprove their own work. But the research held up.,,, The scientists did not set out to disprove Darwin, but, in fact, to learn more about the genetic and ecological uniqueness of fresh water green algae so they could provide conservationists with useful data for decision-making. "We went into it assuming Darwin to be right, and expecting to come up with some real numbers for conservationists," Cardinale says. "When we started coming up with numbers that showed he wasn't right, we were completely baffled.",,, Darwin "was obsessed with competition," Cardinale says. "He assumed the whole world was composed of species competing with each other, but we found that one-third of the species of algae we studied actually like each other. They don't grow as well unless you put them with another species. It may be that nature has a heck of a lot more mutualisms than we ever expected. "Maybe species are co-evolving," he adds. "Maybe they are evolving together so they are more productive as a team than they are individually. We found that more than one-third of the time, that they like to be together. Maybe Darwin's presumption that the world may be dominated by competition is wrong." http://www.livescience.com/45205-data-dont-back-up-darwin-in-algae-study-nsf-bts.html Ocean's most abundant organisms have clear daily cycles - July 10, 2014 Excerpt: Imagine the open ocean as a microbial megacity, teeming with life too small to be seen. In every drop of water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean microbes have their own daily cycles -- not unlike the residents of a bustling city who tend to wake up, commute, work, and eat at the same times.,,, "I like to say they are singing in harmony," said Edward F. DeLong, professor of Oceanography at University of Hawaii,,, What scientists saw was intriguing: different species of bacteria expressing different types of genes in different, but consistent, cycles -- turning on, for example, the type of restorative genes needed to rebuild their solar-collecting powers at night, then ramping up with different gene activity to build new proteins during the day. "The regularity and timing of individual microbial activities is somewhat like a new shift of hourly workers punching in and out of the clock, day after day," DeLong said.,,, "There are some fundamental laws to be learned about how organisms interact, to make the system work better as a whole and be more efficient," DeLong said. http://www.sciencedaily.com/releases/2014/07/140710141539.htm Oceanic microbes behave in a synchrony across ocean basins - March 16, 2015 Excerpt: Researchers have found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite inhabiting extremely different habitats -- the nutrient-rich waters off California and the nutrient-poor waters north of Hawai'i. Furthermore, in each location, the dominant photoautotrophs appear to initiate a cascade effect wherein the other major groups of microbes perform their metabolic activities in a coordinated and predictable way.,,, The bacterial groups common to both ecosystems displayed the same transcriptional patterns and daily rhythms -- as if each group is performing its prescribed role at a precise time each and every day, even though these communities are separated by thousands of miles. "Our work suggests that these microbial communities broadly behave in a similar manner across entire ocean basins and that specific biological interactions between these groups are widespread in nature,",,, "Surprisingly, however, our work shows that these extremely different ecosystems exhibit very similar diel cycles, driven largely by sunlight and interspecies microbial interactions," said Aylward, "This suggests that different microbial communities across the Pacific Ocean, and likely waters across the entire planet, behave in much more orderly ways than has previously been supposed," http://www.sciencedaily.com/releases/2015/03/150316102112.htm

These following sites have illustrations that shows some of the interdependent, ‘life-enabling’, biogeochemical complexity of different types of bacterial life on Earth.,,,

Biologically mediated cycles for hydrogen, carbon, nitrogen, oxygen, sulfur, and iron – image of interdependent ‘biogeochemical’ web http://www.sciencemag.org/content/320/5879/1034/F2.large.jpg Geobiologist Noffke Reports Signs of Life that Are 3.48 Billion Years Old - 11/11/13 Excerpt: the mats woven of tiny microbes we see today covering tidal flats were also present as life was beginning on Earth. The mats, which are colonies of cyanobacteria, can cause unusual textures and formations in the sand beneath them. Noffke has identified 17 main groups of such textures caused by present-day microbial mats, and has found corresponding structures in geological formations dating back through the ages. http://www.odu.edu/about/odu-publications/insideodu/2013/11/11/topstory1 Microbial Mat Ecology – Image on page 92 (third page down) http://www.dsls.usra.edu/biologycourse/workbook/Unit2.2.pdf

,,,Please note, that if even one type of bacteria group did not exist in this complex cycle of biogeochemical interdependence, that was illustrated on the third page of the preceding site, then all of the different bacteria would soon die out. This essential biogeochemical interdependence, of the most primitive different types of bacteria that we have evidence of on ancient earth, makes the origin of life ‘problem’ for neo-Darwinists that much worse. For now not only do neo-Darwinists have to explain how the ‘miracle of life’ happened once with the origin of photosynthetic bacteria, but they must now also explain how all these different types bacteria, that photosynthetic bacteria are dependent on, in this irreducibly complex biogeochemical web, miraculously arose just in time to supply the necessary nutrients, in their biogeochemical link in the chain, for photosynthetic bacteria to continue to survive. bornagain77
