Today, we reviewed some of the characteristics that living things share: organization, growth, development, and reproduction. We viewed a time-lapse video of a salamander developing from a single, fertilized egg cell into a fully-grown organism. In the video, we were able to see the cell dividing, and with each division doubling its number of cells (reproduction/growth). We were able to see the organism form different features, such as gills, legs, a head, etc. (development/organization). We paused the video at key points to discuss these findings.
