Patter of peripatus feet

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 ultimate in powered ships, clean and efficient, cutting through the waves with only the sun to power it. We could donate one of these to the Marshall islands, where sun but not much else is in abundance.

Bats and dolphins have a similar genetic heritage

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...

When cuckoos and their fellow brood-parasites choose their laying site, there is now some evidence that they compete with each other. They have to deal with the host species, but their own species can be their worst enemy.

The history of Americans is found fascinating, even though we have precious little knowledge of it. The momentum builds with this intriguing study of North American language groups and their relationship with rich and poor ecologies.

It might seem disappointing to fond that your Atlantic orcas don’t have the speciation evident in some Pacific pods. However, the great find here is that populations almost certainly have to be physically separated, as well as having different niches, in order for a new species to be evolved.

We think we're special, but more and more creatures are appearing as altruistic, language-capable and downright human. Dolphins of course will be one of the first in many people's minds to demonstrate high-level mental capacity, or in this case, great cognition and lengthy memories.
