Surprisingly, dinosaur teeth and human teeth have a lot in common. Scholars discover how teeth form during embryonic development. They then compare fossil evidence of the similarities of teeth of ancient species.

Viewers follow the development of a human embryo, the brain, and the number of neurons at each stage. They learn when the brain stops growing and the importance of neural connectivity.

Even today's stem cells have a history—and it's more than 30 years old! Learn how stem cell lines grow in a lab. Observe the various experiments completed to determine how cells grow in human embryos.

At what point in the fertilization process do stem cells turn into an embryo? Viewers observe the development of an embryo from egg to fertilization to development into a fetus. The narrator stresses the role of cell division,...

Cell specialization is amazing! How do they know what they should become? A video from an interesting biology playlist examines the process of cell specialization. Content includes where we find specialized cells, types of specialized...

Need help putting together an uncommonly good unit about common ancestry? Check out a video that covers NGSS standard LS4A, Evidence of Common Ancestry and Diversity. Topics include ways to convey similarities and differences between...

Computers help doctors determine the most viable embryos. Researchers discovered the rate of embryo growth has a direct link to its sustainability. Pupils discover how doctors apply this research to help their patients.

Stem cell research and ethics are hotly debated, but many pupils don't really know what a stem cell is. The video describes what they are, why they are different than other cells, and where they can be found. The video continues with how...

Do you know what Sonic hedgehog is? Yes, it is a video game character, but it is also a protein that controls how your fingers develop. A paleontologist discusses the development of the arm and hand, beginning with fish and ending...

All naval oranges are clones and come from a single tree in Brazil. Viewers see how the human genome can be manipulated in a video that also discusses cloned produce, cloned animals, identical twins, and wraps up by talking about...

With over five million babies being born through in vitro fertilization in the last 40 years, sex education is taking on a whole new look. After first walking through natural process of reproduction, this short video goes on to...

Three-dimensional animation zooms in on human development as it begins in the female ovaries. The animated egg changes and forms as you watch it travel down the fallopian tube into the uterus.

The journey of a fertilized egg is illustrated as it travels from the fallopian tube to the uterus. Cell division is explained and the miracle of life is shown.

In this video, Paul Andersen describes several types of evidence for common ancestry. This evidence is contained in the fossils, embryos and molecules of living organisms. Even though life on our planet is incredibly diverse there are...
