Adaptations
Inquiry question: How do adaptations increase the organism’s ability to survive?

'Adaptations' Worksheet
An organism’s adaptations are a result of the genes the organism inherits from its parents.
The proportion of well-adapted organisms in a population can increase over the generations by the process of evolution by natural selection.

There are three different types of adaptations:
Behavioural - responses made by an organism that help it to survive/reproduce
Physiological - a body process that helps an organism to survive/reproduce
Structural - a feature of an organism’s body that helps it to survive/reproduce

FIRST HAND INVESTIGATIONS OF ADAPTATIONS
Investigation of 'moss' that was located on the concrete slab of the LC at St Pauls - structural adaptations including root and leaf structure were investigated using the binocular microscopes

In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship's naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos. He filled dozens of notebooks with careful observations on animals, plants and geology, and collected thousands of specimens, which he crated and sent home for further study.
Darwin later called the Beagle voyage "by far the most important event in my life," saying it "determined my whole career." When he set out, 22-year-old Darwin was a young university graduate, still planning a career as a clergyman. By the time he returned, he was an established naturalist, well-known in London for the astonishing collections he'd sent ahead. He had also grown from a promising observer into a probing theorist. The Beagle voyage would provide Darwin with a lifetime of experiences to ponder—and the seeds of a theory he would work on for the rest of his life.

Perform a second-hand investigation on:
the observations and the collection of data that Darwin collected to support the theory of evolution by Natural Selection from the Finches of the Galapagos Islands.
the observations and the collection of data that Darwin collected to support the theory of evolution by Natural Selection from Australian flora and fauna (For fauna, focus on the Platypus. For flora, focus on the Nullabor Plain - journal article attached on this to the left of this text box)
