The 2005 Schol Bio paper included the following question. The three examples shown represent just some of the diversity found in bony fish. Use the diversity of the fish and/or any other named group(s) to discuss the following statement: 'Diversity is the end product of evolution.'

Here's a link to a set of articles that summarise talks on various aspects of evolution research. They're straightforward & easy to read, & should give you some interesting additional background to some recurring questions.
Those of you who've come to one of my Scholarship preparation days may have noticed that I've got a bit of a bee in my bonnet about pseudoscience. It really annoys me when I see science being mis-used to sell a product or promote a particular point of view. A good friend of mine has just sent me one of the worst examples I've seen for a while, & I thought it could be useful to share it with you. Here's the lead-in to the article...
I think it was Thomas Edison who said, Genius is 1% inspiration and 99% perspiration. In other words, success (in any field) requires a lot of hard work. (True also of preparing for Scholarship exams.) Now here's another science-relevant quote...
Here's something for your reading list: an excellent extended essay on how our view of human evolution, & of our place in the world, has changed over time. Enjoy!
Oops! I forgot... but anyway, Happy Darwin Day for the 9th of February. Charles Darwin would have been 199 years old. Next year's the 200th anniversary of his birth & also the 150th anniversary of the publication of The Origin of Species; I'll have to organise some birthday celebrations :-)
I know you may read this & think I'm a bit odd... But anyway - just after the L3 exam I was talking with a student & she said, why did there have to be cockroaches in a question? My answer: why not? They're just another animal (even if many people don't like them much) & the examiner had obviously chosen this particular example to tease out understanding of evolutionary processes. (Could have been worse - they might have chosen tapeworms!)
I mean, extinctions of giant fish, not giant extinctions of fish! This is about a paper that I read last year & put aside as a 'general interest' topic for when I was looking for something to write about.
Ages ago I saw an item on TV about cuttlefish - one of the neat things I took away from it was how cuttlefish and other cephalopods (octopus & squid) use colour to communicate, and how precise their control of skin coloration is. And I would tell my students about it, but I didn't have the pictures! Well, take a look at this...
