How did the first reptiles evolve on Earth?
About 300 million years ago, amphibians evolved into reptiles. These reptiles continued to adapt to their environment. They developed a better way of breathing than amphibians – amphibians breathe by moving their throat muscles, but the dinosaurs moved the muscles below the rib cage and abdomen, just like us. As a result, they could take in more air.

Essential Photography Tips
How do you get images for a portfolio
Shoot free and shoot cheap. Many of the images in a wedding portfolio are still life pictures that can be created without a wedding. Get some flowers and practice macro photography. Shoot your own wedding ring. Create evocative portraits of family members and friends. Practice using different styles photojournalism, romantic, fun. Photograph local buildings to illustrate that you can do architecture. I recently viewed the website of a photographer who did great architectural photos of a Dunkinand Donuts.
I shot my first wedding for a friend, who agreed to pay for half of my film costs. What a bargain for both of us I also had a friend in politics, and shot political portraits for his campaign. And somewhere I met the owner of an exercise business and shot her facility and staff after hours. These free photos were used by the people in them, and gave me invaluable experience. NOTE WELL: When you present your pictures to your customer, show them only the really good ones and edit out the duds. The brochures and prints from these sessions were an important part of my portfolio for years.
