Lyrics:
Oh, a fish-like thing appeared
among the annelids one day,
It hadn't any parapods
or setae to display.
It hadn't any eyes or jaws
or ventral nervous chord.
But it had a lot of gill slits
and it had a notochord.
Chorus:
It's a long way from amphioxus,
it's a long way to us.
It's a long way from amphioxus
to the meanest human cuss.
Good-bye to fins and gill slits,
welcome lungs and hair.
It's a long, long way from amphioxus,
but we all came from there.
It wasn't much to look at
and it scarce knew how to swim.
And Nories was very sure
it hadn't come from him.
The Mulluscs wouldn't own it
and the Arthropods got sore.
So the poor thing had to burrow
in the sand along the shore.
He burrowed in the sand
before a crab could nip his tail.
And he said, "Gill slits and
myotomes are all to no avail."
"I've grown some metapleural folds
and sport and oral hood.
But all these fine new characters
don't do me any good."
Chorus
He sulked awhile down in the sand,
without a bit of pep;
Then he stiffend up his notochord
and said, "I'll beat 'em yet!"
"Let them laugh and show their ignorance,
I don't mind their jeers."
"Just wait until they see me
in a hundred million years."
"My notochord shall change
into a chain of vertabra,
And, as fins, my metapleural folds
will agitate the sea."
"My tiny dorsal nervous chord
shall be a mighty brain.
And the vertabrates shall
dominate the animal domain."
Chorus
This is my last upload for 2015, so Happy New Year. May 2016 be a joyful, peaceful and prosperous year for you.
For a week or so now, I have been asking my subscribers if they can make some suggestions for songs that I might be interested in singing as I have hit a bit of a hiatus and am struggling to think of songs that I have not already uploaded.
Marian Gabriel has responded and suggested that I look at some of the songs from the repertoire of Sam Hinton. This is one of the songs he sang. The lyrics were written by Philip H Pope and set to the tune of "It's A Long Way To Tipperary" and has become the official theme song for the Biological Sciences Collegiate Division at The University of Chicago.
There used to be a Marine Biological Station in Port Erin, (where I have lived most of my life), which was a branch of Liverpool University, so I expect many of the students and staff who worked there would recognize the names and terms that are included in the lyrics of this song, but for those of us who are not marine biologists, here is a glossary to help explain some of them:
Glossary
Nereus: was the eldest son of Pontus (the Sea) and Gaia (the Earth), who with Doris fathered the Nereids and Nerites, with whom Nereus lived in the Aegean Sea.
Annelids: are ringed worms or segmented worms. They are a large phylum, with over 17,000 extant species including ragworms, earthworms, and leeches.
Parapods: In annelids, parapodia are paired, un-jointed lateral outgrowths that bear the chaetae.
Chaetae: A chaeta or cheta (see spelling differences) is a chitinous bristle or seta found on an insect, arthropod or annelid worms such as the earthworm, although the term is also frequently used to describe similar structures in other invertebrates.
Notochord: is a flexible rod made out of a material similar to cartilage. If a species has a notochord, it is, by definition, a chordate.
Amphioxus: any of certain members of the invertebrate subphylum Cephalochordata: With about twenty-five species inhabiting shallow tropical and temperate oceans, the Cephalochordata are a very small branch of the animal kingdom. Known as lancelets or as amphioxus (from the Greek for "both [ends] pointed," in reference to their shape), cephalochordates are small, eel-like, unprepossessing animals that spend much of their time buried in sand. However, because of their remarkable morphology, they have proved crucial in understanding the morphology and evolution of chordates in general -- including vertebrates.
Myotomes: A myotome is the group of muscles that a single spinal nerve root innervates.
Metapleural folds: ... gill slits are enclosed by folds of the body wall, the metapleural folds, to form a body cavity known as the atrium.

Ants are distinct in their morphology from other insects in having elbowed antennae, metapleural glands, and a strong constriction of their second abdominal segment into a node-like petiole. The head, mesosoma, and metasoma are the three distinct body segments. The petiole forms a narrow waist between their mesosoma (thorax plus the first abdominal segment, which is fused to it) and gaster (abdomen less the abdominal segments in the petiole). The petiole may be formed by one or two nodes (the second alone, or the second and third abdominal segments).
Like other insects, ants have an exoskeleton, an external covering that provides a protective casing around the body and a point of attachment for muscles, in contrast to the internal skeletons of humans and other vertebrates. Insects do not have lungs; oxygen and other gases such as carbon dioxide pass through their exoskeleton via tiny valves called spiracles. Insects also lack closed blood vessels; instead, they have a long, thin, perforated tube along the top of the body (called the "dorsal aorta") that functions like a heart, and pumps haemolymph toward the head, thus driving the circulation of the internal fluids. The nervous system consists of a ventral nerve cord that runs the length of the body, with several ganglia and branches along the way reaching into the extremities of the appendages.
Head
An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. Compared to vertebrates, most ants have poor-to-mediocre eyesight and a few subterranean species are completely blind. Some ants such as Australia's bulldog ant, however, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a metre away.
Two antennae ("feelers") are attached to the head; these organs detect chemicals, air currents, and vibrations; they also are used to transmit and receive signals through touch. The head has two strong jaws, the mandibles, used to carry food, manipulate objects, construct nests, and for defence. In some species a small pocket (infrabuccal chamber) inside the mouth stores food, so it may be passed to other ants or their larvae.
Legs
All six legs are attached to the mesosoma ("thorax"). A hooked claw at the end of each leg helps ants to climb and to hang onto surfaces.
Wings
Most queens and the small number of drones in a colony (the male ants), have wings; queens shed the wings after the nuptial flight, leaving visible stubs, a distinguishing feature of queens. Wingless queens (ergatoids) and males occur in a few species, however.
Polymorphism
Seven Leafcutter ant workers of various castes (left) and two Queens (right)
In the colonies of a few ant species, there are physical castes—workers in distinct size-classes, called minor, median, and major workers. Often the larger ants have disproportionately larger heads, and correspondingly stronger mandibles. Such individuals sometimes are called "soldier" ants because their stronger mandibles make them more effective in fighting, although they still are workers and their "duties" typically do not vary greatly from the minor or median workers. In a few species the median workers are absent, creating a sharp divide between the minors and majors. Weaver ants, for example, have a distinct bimodal size distribution. Some other species show continuous variation in the size of workers. The smallest and largest workers in Pheidologeton diversus show nearly a 500-fold difference in their dry-weights. Workers cannot mate; however, because of the haplodiploid sex-determination system in ants, workers of a number of species can lay unfertilised eggs that become fully fertile, haploid males. The role of workers may change with their age and in some species, such as honeypot ants, young workers are fed until their gasters are distended, and act as living food storage vessels. These food storage workers are called repletes. This polymorphism in morphology and behaviour of workers initially was thought to be determined by environmental factors such as nutrition and hormones that led to different developmental paths; however, genetic differences between worker castes have been noted in Acromyrmex sp. These polymorphisms are caused by relatively small genetic changes; differences in a single gene of Solenopsis invicta can decide whether the colony will have single or multiple queens. The Australian jack jumper ant (Myrmecia pilosula) has only a single pair of chromosomes (with the males having just one chromosome as they are haploid), the lowest number known for any animal, making it an interesting subject for studies in the genetics and developmental biology of social insects.

Ants are distinct in their morphology from other insects in having elbowed antennae, metapleural glands, and a strong constriction of their second abdominal segment into a node-like petiole. The head, mesosoma, and metasoma are the three distinct body segments. The petiole forms a narrow waist between their mesosoma (thorax plus the first abdominal segment, which is fused to it) and gaster (abdomen less the abdominal segments in the petiole). The petiole may be formed by one or two nodes (the second alone, or the second and third abdominal segments).
Like other insects, ants have an exoskeleton, an external covering that provides a protective casing around the body and a point of attachment for muscles, in contrast to the internal skeletons of humans and other vertebrates. Insects do not have lungs; oxygen and other gases such as carbon dioxide pass through their exoskeleton via tiny valves called spiracles. Insects also lack closed blood vessels; instead, they have a long, thin, perforated tube along the top of the body (called the "dorsal aorta") that functions like a heart, and pumps haemolymph toward the head, thus driving the circulation of the internal fluids. The nervous system consists of a ventral nerve cord that runs the length of the body, with several ganglia and branches along the way reaching into the extremities of the appendages.
Head
An ant's head contains many sensory organs. Like most insects, ants have compound eyes made from numerous tiny lenses attached together. Ant eyes are good for acute movement detection, but do not offer a high resolution image. They also have three small ocelli (simple eyes) on the top of the head that detect light levels and polarization. Compared to vertebrates, most ants have poor-to-mediocre eyesight and a few subterranean species are completely blind. Some ants such as Australia's bulldog ant, however, have excellent vision and are capable of discriminating the distance and size of objects moving nearly a metre away.
Two antennae ("feelers") are attached to the head; these organs detect chemicals, air currents, and vibrations; they also are used to transmit and receive signals through touch. The head has two strong jaws, the mandibles, used to carry food, manipulate objects, construct nests, and for defence. In some species a small pocket (infrabuccal chamber) inside the mouth stores food, so it may be passed to other ants or their larvae.
Legs
All six legs are attached to the mesosoma ("thorax"). A hooked claw at the end of each leg helps ants to climb and to hang onto surfaces.
Wings
Most queens and the small number of drones in a colony (the male ants), have wings; queens shed the wings after the nuptial flight, leaving visible stubs, a distinguishing feature of queens. Wingless queens (ergatoids) and males occur in a few species, however.
Polymorphism
Seven Leafcutter ant workers of various castes (left) and two Queens (right)
In the colonies of a few ant species, there are physical castes—workers in distinct size-classes, called minor, median, and major workers. Often the larger ants have disproportionately larger heads, and correspondingly stronger mandibles. Such individuals sometimes are called "soldier" ants because their stronger mandibles make them more effective in fighting, although they still are workers and their "duties" typically do not vary greatly from the minor or median workers. In a few species the median workers are absent, creating a sharp divide between the minors and majors. Weaver ants, for example, have a distinct bimodal size distribution. Some other species show continuous variation in the size of workers. The smallest and largest workers in Pheidologeton diversus show nearly a 500-fold difference in their dry-weights. Workers cannot mate; however, because of the haplodiploid sex-determination system in ants, workers of a number of species can lay unfertilised eggs that become fully fertile, haploid males. The role of workers may change with their age and in some species, such as honeypot ants, young workers are fed until their gasters are distended, and act as living food storage vessels. These food storage workers are called repletes. This polymorphism in morphology and behaviour of workers initially was thought to be determined by environmental factors such as nutrition and hormones that led to different developmental paths; however, genetic differences between worker castes have been noted in Acromyrmex sp. These polymorphisms are caused by relatively small genetic changes; differences in a single gene of Solenopsis invicta can decide whether the colony will have single or multiple queens. The Australian jack jumper ant (Myrmecia pilosula) has only a single pair of chromosomes (with the males having just one chromosome as they are haploid), the lowest number known for any animal, making it an interesting subject for studies in the genetics and developmental biology of social insects.
