Latest Challenges to the Teaching of Evolution

Biology teachers are of special significance because many high school students take biology but no other science classes.

As I do the arithmetic, that means an astounding 72 percent of our teachers don't teach the organizing principle at the base of modern biological science.

...Biology's easy you see.
Simply rote learn catalogues of long names ...

....in 2005 my team and I were out hunting for fish fossils in the tall, grassy paddocks of Gogo Station, a vast cattle ranch located in the heart of northwestern Australia... But some 375 million years ago, during the Late Devonian period, a shallow sea covered the area and Gogo was home to an enormous tropical reef that teemed with marine life, including a plethora of primitive fishes...

When a topic becomes all lonus/spendius all the time I eventually have to tune out.

.. It's about time the debating table got rid of all the clutter like .... and any others who agree with their sexually induced posturing ..

I love disagreement, it fills the topic with many views. However, when the entire communication is an obvious cry for attention and the writing style is disjointed and full of run ons ,and its gone on unchanged for 5 years, well. I see no reason to believe that an individual will "grow up", SO "ignore" is a great feature. Beating ones head against a wall expecting a different outcome each time may be what Australians respect, but in my neck of the woods, we know that hitchin a dray horse to a sulky is gonna give you a bad ride.

Anyway, Im having fun over on the thread with the "fossil" brain.

Most fishes are egg-layers, but many bear living young. Live-bearing fishes may be ovoviviparous, in which the eggs essentially simply hatch within the female, or viviparous, in which the unborn young are supplied nourishment through the mother's tissues. In some ovoviviparous fishes the embryo develops in the egg while the egg is still within its follicular covering within the ovary, and ovulation (or release of the egg) and birth occur at the same time. In other ovoviviparous forms the eggs are released from the protective follicles into the cavity of the hollow ovary, where development continues. In some viviparous fishes the walls of the egg follicle are in intimate contact with the embryo, supplying it with nourishment. In the viviparous sharks, a part of the oviduct, or egg channel, is developed into a uterus, where the modified yolk sacs of the young are closely joined to pockets within the uterus.

In live-bearing fishes and in some egg-layers, fertilization occurs internally, and methods have been evolved for introducing the sperm into the female's body. In sharks the pelvic fins of the male are modified into intromittent organs called myxoptergia, and in the male topminnows the anal fin is modified into a similar-functioning intromittent organ called the gonopodium.

At least three modes of reproduction--heterosexual, hermaphroditic, and parthenogenetic--are found in fishes. In the most common form, heterosexual reproduction, there are separate male and female parents, but even here there is considerable variation. In some live-bearing fishes, the female is able to store sperm for up to 8 or even 10 months, and this sperm is used to fertilize new batches of eggs as they develop. In some cases, a female may carry sperm from several males at once.

In hermaphroditic reproduction, a single fish is both male and female, produces both eggs and sperm (either at the same time or at different times), and mates with other similar hermaphroditic fishes. External self-fertilization occurs in one hermaphroditic fish, which sheds egg and sperm simultaneously. In another, internal self-fertilization may occur. In certain fishes there is a time sequence of hermaphroditism, young fishes reversing their sex as they grow older.

In parthenogenetic reproduction, unfertilized eggs develop into embryos. This is known to exist in at least one fish species, Poecilia formosa, of the Amazon River; however, even though development proceeds without fertilization in some of these females, mating with a male is still required to stimulate egg development.

Parental care also shows great diversity. Some fishes, like the Atlantic herring, form huge schools of males and females and freely shed their eggs and sperm (milt), and then abandon the eggs. Other fishes build nests and care for both the eggs and newly hatched young. Others have evolved methods of carrying the eggs with them, commonly in their mouths, but also in gill cavities or in special pouches on the body.

you also seem to be painting with a broad brush in my opinion!
