聽力文本

 Narrator: Listen to a conversation between a student and her academic advisor.

Advisor: What’s on your mind, Sara?

Sara: Well, I’ve been taking a couple of biology classes this semester, and I really like it and well, I’d decided I’d like to change my major field of study and get a degree in biology instead of math.

Advisor: Oh okay. But you only have two more years here before you’re scheduled to graduate. And you know that is probably not enough time to take all the courses you need. So, if you change your major you may end up graduating late.

Sara: Well, but you know the biology department summer program, the one just for undergraduates?

Advisor: Sure, but the application deadline has already passed.

Sara: Oh yes, I know. What I wanted to ask is, well, do you know of any similar programs elsewhere where I can take the courses and have the credits transferred here?

Advisor: Okay. I see now. Well, a few of our students have attended the summer program at the York Institute of Technology on the other side of the city. Their summer program in the biology is a good one. They offer a variety of areas to focus on like cell biology, marine biology, even biotechnology. It will all be on their website.

Sara: Wow! Sounds good!

Advisor: You could take two courses there this summer which would apply to your degree here.

Sara: Oh, but I would need to take three to graduate on time.

Advisor: Well, maybe you can do the York Summer Program and an independent study project with one of your biology professors here.

Sara: Okay.

Advisor: But many professors here have already left for the summer, so you might have difficulty finding someone to supervise you this summer. But maybe you could schedule up for next summer.

Sara: Now, that would work. I will do that. Do you know when the application deadline is for the York?

Advisor: It’s a week from now.

Sara: Guess I will have to act fast. But one thing. When I got my grades back last semester, the grades from my mathematical modeling class was wrong. It was lower than what I actually earned. My professor submitted the paperwork to get it corrected but he said it could take us a week before the right grade shows up on my official records. What if York Institute wants to see my grades when I apply?

Advisor: Well, if it’s not corrected in time, ask your professor to write a letter explaining the situation and include it in your application. That should be acceptable.

Models of Egg Development

Several different theories have been put forward to explain how the hard-shelled eggs of land-dwelling reptiles (e.g. lizards) evolved from the soft eggs that amphibians (e.g. frogs and toads) lay in water. The Romer model of egg development is named after the late Alfred Romer, a paleontologist who also became director of the Harvard University Museum of Comparative Zoology. His specialty was early reptiles because, he felt, they were the key to understanding the great reptile diversification seen in the Late Paleozoic and Mesozoic Eras (around 230 million years ago). Romer’s hypothesis was that some aquatic amphibians that is, amphibians living in water called anthracosaurs began to lay their eggs on land at about the time that they were evolving reptile-like skeletal features. Indeed, some of these early amphibians and earliest reptiles are so similar in their skeletons that the exact transition point from one to the other is still difficult to determine. Eventually, though, the transition was made, but these early reptiles remained aquatic. The advantage for laying eggs on land was primarily to avoid the aquatic larval (pre- adult) stage during which immature amphibians live exclusively in water with its inherent risk of predators and drying of ponds. However, the land has its own set of dangers, not least of which is the drying effect of the atmosphere. To cope with these problems, a series of protective membranes developed around the egg, including a hard shell. Only later did the reptiles completely abandon an aquatic lifestyle.

Another hypothesis was proposed by German paleontologist Rolf Kohring, whose specialty is fossil eggs.

In Kohring’s model, amphibians during the Mississippian epoch (360-320 million years ago) spread into nutrient-poor or cooler water. Because of the harsher conditions, eggs were produced with larger yolks, that is, more nutrients for the embryo. With larger yolks, the eggs were bigger, and fewer of them could be produced by the female hundreds rather than thousands. ■ To keep the larger egg intact, one or more membranes were developed, including one that surrounded and protected the egg. ■ This outer membrane provided a place to safely store calcium ions, which are poisonous. ■ Accumulating the calcium in a hard shell then made it possible for the egg to be laid on land (it was pre-adapted to be laid there.) ■

One other model we should consider is the anti-predator hypothesis proposed by Gary and Mary Packard to explain the evolution of the hard-shelled egg. Their model was not concerned with the development of membranes surrounding the egg but continues the story after these membranes appeared. The Packards assume that the earliest reptiles laid leathery shelled eggs on very wet ground where they could absorb water during the embryos’ growth. But life on the ground is not without hazards, based on studies of modern reptiles with leathery shelled eggs. Predatory insects and microbes can be a major cause of egg mortality. To counter this loss of eggs, some of the early reptiles began secreting a thin calcareous (containing calcium carbonate) layer. This hard layer gave the embryos a better chance of surviving until hatching. And these survivors in turn would probably leave more progeny once a few of them reached reproductive age. In time, a thicker, more resistant shell developed. However, a thicker eggshell meant that less water could be absorbed for the needs of the embryo. To compensate, larger eggs were produced, containing a great deal more albumen (egg white, a water-soluble protein). At this point, the rigid eggshell had reached the bird egg level of complexity.

Mary Packard presented yet another model with her colleague Roger Seymour. They note that amphibian eggs can never get very large because the gelatin coat surrounding the developing larva is not very good at transmitting oxygen. Because of this restriction, we will never see frog eggs the size of a chicken’s. For Packard and Seymour, the major evolutionary breakthrough in reptile eggs was the elimination of the thick gelatin coat and replacing part of it with a fibrous membrane. This change allowed larger eggs to be developed.
