Flores Human Dwarf Debate

Flores Human Dwarf Debate

Posted Sun, 02 Feb 2014 17:01:01 GMT by Dave Armstrong

The feet of the Flores hominid might be more conclusive than the small head, if we ever come to better conclusions about its ecology, niche or even what it ate. The point is, we can’t even decide on its species and it's only 18,000 years old.

Flying and genome size: it’s true about the reduction!

Flying and genome size: it’s true about the reduction!

From humming birds to eagles, the birds have diversified their niches worldwide. Their genome however is reduced compared to us earthbound creatures!

When they rage at the dingo, the ignorant fail to appreciate what many of us have thought. The need for such predation and scavenging is always present, plus we all need more natural systems than the awesome monoculture we get from tropical oil palms to “recyclable” spruce plantations.

How fish evolved their migratory habits

You would expect an evolutionary shift to be a trend, but in one great family of fish, there is little evidence that lightning strikes twice, especially in the same freshwater ecosystem!

We can catalogue all the live and some extinct species on earth. The sooner we know all those insects and marine creatures, the quicker we can deal with conservation management in the most efficient ways possible.

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.
