Scientific American- 60 Second Science

In Mass Media, we browsed through podcasts of interesting stories on Scientific American 60 Seconds of Science. I picked the “13,000-Year-Old Footprints under West Coast Beach”. I created a new project in Adobe Premiere, and named it “60 Seconds Science.” I downloaded the podcast and imported into the app. Later on, I found pictures corresponding to the podcast and edited them by cropping, using filters, and adding text to give the viewer a better understanding of the audio. After changing the pictures a bit, I imported them into Adobe Premiere and organized by arranging them so they go along with the audio. I made sure that the timing for each one was precise by changing the length of time that each picture was going to be presented. I also made an opening and closing title and gave credit to the reporter, Christopher Intagliata, and overall, Scientific American. Lastly, I put finishing touches on the video and exported it. This video is uploaded onto YouTube.

Here is the transcript of the podcast that I used:

During the last ice age, the northern half of North America was blanketed by ice. But along the Pacific coast of Canada, some land remained bare…a place where animals and plants could thrive. And humans too.

Archaeologists have found stone tools and cave sites 12,000 to 13,000 years old in the coastal Pacific Northwest. One find was a mastodon rib with a bony weapon in it. And now scientists at the Hakai Institute and the University of Victoria have made a spectacular discovery: clay soil, trampled by human feet—the oldest footprints uncovered in North America.

Researchers were digging several feet below a modern-day beach on British Columbia’s Calvert Island, about 250 miles northwest of Vancouver, when they discovered tracks. They found 29 in all. Some had toes, arches and heel prints—indicating the people who left them were probably barefoot. And using a shoe size measurement chart—like the ones you find in a shoe store—they determined that the footprints likely belonged to a child and two adults. Who lived and walked the area some 13,000 years ago.

The results are in the journal PLOS ONE. [Duncan McLaren et Al., Terminal Pleistocene epoch human footprints from the Pacific coast of Canada]

The tracks are not in a line, like the famous Laetoli footprints in Tanzania. Instead, they’re facing different directions, suggestive of people gathering. Or perhaps, the authors write, they could be the footprints of people getting out of a boat, headed towards higher and drier land. Still on the move.
