Uruguayan fish show how they evolve

Fish diversify into thousands of species, especially cichlids in African lakes. Mammals and birds can show equal diversity sometimes, so it would be intriguing to find more vertebrate classes subjected to investigations such as these, proving some genetic matches for lost and current animals we want to know more about.

Birds are known for putting a lot of effort into their mating displays. In the tropics however, energy is at a premium, and sexual selection has been known to be more or less illogical in the abnormal effects it has on male display!

The way in which cephalopods and chameleons communicate is colour-based. More study is needed on how much information is passed on. The physiology, the status and the “drive” can be explained now by rate change and colour brightness in different parts of the anatomy

The foresight of some geologists has adjusted our treatment of politicians on several energy extractions and reservoir projects. They seem to be correct in blaming earthquakes on human interference, but can Chinese, Spanish or New Zealand politics afford to take note of dire warnings?

Not well known or noticed, some of the oldest landlubbers on the planet are fascinating as well as useful. They show us when and how the continents spread out in this paper. Have a look at the Onychophora, the velvet 'worms' or Peripatidae!

When humans meet, the interbreeding and cross-cultural exchanges show up in history as major advances. When Neanderthals met, it was often only as small family groups, as large tribes are not recorded. If they met for dinner though, the outcome may not have been as you would have thought.

The telling of stories was the source of history, legends, and even science in some cases. This study of things fairy-like and fantastic is not about the child; it relates how modern technique can uncover ancient culture and how it really worked.

We have this need to understand how our ancestors developed into something beyond the chimpanzee. The problem of lack of skeleton evidence is avoided here with some new techniques of isotope recognition within tooth enamel.

Out there in the Pacific and the other oceans, the mid-depth temperatures are still increasing rapidly. Science techniques have discovered the temperature regime changes over 10, 000 years and it is certainly warming up out there!

We worry about how human species colonised the rest of the world after leaving Africa. There is so little evidence, we have to rely on the latest technology to try and unravel the fascinating stories of travel and survival these early peoples must have had. Here, 50,000 years ago, is conjecture about what would have been an almost impossible voyage.

We can visualise distant ancestral forms of many organisms by imagining similar species alive today, or complete fossils. Here the scarcity of evidence on early mammalian teeth makes it difficult, but not impossible, to show how incredible events shaped our past into the flower, insect and mammal-dominated Paleocene.

The thought of bat and whale being related because they have similar hearing is incorrect. If we study a range of species, though, the evolutionary convergences of many kinds of sensory structures is very involving. What's next? Our chimpanzee friends will be developing their typing skills before we know it!

The fish that benefit from trawling disturbance eat invertebrates such as annelids. Other invertebrates, especially the heavy species, are decimated by trawling and need much more protection by modifying the trawling gear or simply preventing such damage to the environment.

The geochemists get a poor press, so they must have decided to soup up their theories and grab some oxygen for their reputation. The claim is that being impossible on earth, ribose sugars can only have been synthesised on Mars, 4 billion years ago. And then...
