Let’s have Fun – go in the Polls !

Okay, it’s time to slow down a bit and have some fun or entertainment by having your say in one of the “Fascinating Animals” and / or “Our Lovely World” Polls.

It’s easy – just click on the Titles above or on the Links below to join in, and to view the Results.

I’ll even place a Poll in this Post.  Don’t be lethargic or stick-in-the-mud, your say is “annonymous” and the results could be quite interesting.

NOW, for this Post’s Poll !

In the Beginning was ……  no, you CAN’T choose Aliens or God or Nothing or the Void, because the Poll is actually about either Light or Sound

I once attended an Astrology course and had an argument with the teacher about whether Light or Sound was in the VERY beginning, the first thing emanating from the “Void”.  You may choose to say there was both Light and Sound at the same time, but it will be interesting to see how many choose only “Light” and how many choose only “Sound.”

 

This Post  about what physicist Professor Brian Cox says about “what makes the universe up or down” may help you answer.

By the way, the reason for my answer can be found by clicking  HERE.

ENJOY, if you do, and share with your friends.

Polite discussion about this Poll is invited.  You will need a WordPress Username to comment (which is a requirement to try to stop spammers from posting silly stuff on this Blog).

Did you know that in 1966, British economist and writer, Barbara Mary Ward coined the term “Spaceship Earth?”   Read about that here.

Cladograms & Evolution – We are all related

Brontosaurus

Phylogenetics orPhylogenetic systematics is a discipline and a field of biology that aims to identify and understand the evolutionary relationships among the many different kinds of life forms on earth, both living (extant) and dead (extinct)Cladistics uses an understanding of phylogenetics to look at the “Tree of Life” and uses a type of diagram called a Cladogram to represent branched “evolutionary relationships” or phylogenies.

Phylogenies are lists or diagrams that show the evolutionary paths taken by populations of organisms through many generations and over long periods of time.

Nomenclature is the devising or choosing of names for things, especially within a branch of science. Systematics or Taxonomy is the branch of biology that deals with classification and nomenclature of organisms or life forms.  A binomial (or two word) nomenclature is used to label and identify known species, using a Genus name and a Species name.  Please see    this   post here for in depth information about TAXONOMY.

Thylacine – Tasmanian Tiger (Thylacinus cynocephalus)

Thylacine   (Thylacinus cynocephalus)

Distribution:   Prehistorically, Australia and New Guinea; Historically, Tasmania.

Last Record:   Night of 7 September 1936.

The thylacine was the largest marsupial predator to have survived into historic times. Before the introduction of the dingo to mainland Australia around four thousand years ago it was widespread on the mainland and in New Guinea. When first encountered by Europeans in the early nineteenth century it was restricted to the island of Tasmania. There, however, it occurred in a variety of habitats, but not apparently the dense rainforests of the southwest.

Thylacines were rather wolf-like in shape, males reaching around thirty-five and females twenty-five kilograms in weight. They seem to have hunted singly, in pairs and in family groups (male, female and one to three young), pursuing wallabies and other prey by scent, eventually running them to exhaustion or into ambush.

Lairs were often located among rocks, and young stayed with the female until they were well grown and able to hunt independently. The Tasmanian Aborigines occasionally hunted them, but would build a curious shelter over the bones, believing that if they were rained upon then very bad weather would follow.

What is “Horsepower”?

The term “horsepower” has its origins in the days when horses were integral to the successful activities of human beings.

Horsepower is defined as work done over time. The exact definition of one horsepower is 33,000 lb.ft./minute. Put another way, if you were to lift 33,000 pounds ( or 14,968 kilogram) one foot over a period of one minute, you would have been working at the rate of one horsepower. In this case, you’d have expended one horsepower-minute of energy.

Compared to one horsepower, my physical effort is very feeble.  I can pick up a box weighing 15 kg from the ground and raise it two feet off the ground in a second or two.  Multipy that out to cover 60 seconds, and it means perhaps something like 900 kg one foot or more over one minute.  In other words, if I am interpreting things correctly, my work capacity is 6 percent ( 900 divided by 14,968 ) of what one horse can do, in the example pictured below.

The Age of the Mammals from 65 million years ago (mya)

Mammoths

65 milion years ago (mya) the Cenozoic Era began in the time-scale of geological units.  Each Era is divided into Periods of time, and each Period of the Cenozoic Era is divided into Epochs of time.   Please click on the link below for a diagram of the Periods and Epochs in the Cenozoic Era, and for important information about the rise of the Mammals.  This link below shows that the last Ice Age ended 10,000 years ago and the time period (epoch) since then is called the Holocene Epoch.  There has been a series of “ice ages” over billions of years, with the “Great Ice Age” occurring during the Pleistocene Epoch of the Cenozoic Era, 1.8 million to 10,000 years ago.

The dinosaurs had become extinct and now it was the Age of the Mammals, arising in the Palaeocene Epoch of the Cenozoic Era, 65 to 55 mya; with the modern line of human beings (from the genus Homo) developing 1.6 mya to 2 mya.  During the Pleistocene Epoch of the Cenozoic Era, there were four completely separate glacial advances in North America.  The advances were separated by long intervals of ice withdrawal, sufficient to permit the previously occupied area covered by ice to be reoccupied by plants and animals.   Glaciation severely affected life on the earth.   Animal and plant life was forced out of vast portions of the land covered by continental ice sheets. Large-scale migrations must have taken place as the ice sheets grew and climatic changes occurred.
