    What can DNA tests really tell us about our ancestry? - Prosanta Chakrabarty

    Dig into the science of how ancestry DNA tests work, their accuracy, and why tracing ancestry is so complicated. Uploaded 09-06-20 -- Two sisters take the same DNA test.

    Can you unravel the savanna mystery? - Cella Wright

    Explore how big-headed ants have changed an entire ecosystem in Kenya, from its insects and plants to its biggest predators. -- In the early 2000s, one of the world’s most widespread invasive species landed in Kenya’s Laikipia Plateau: big-headed ants. They expanded rapidly into super-colonies, preying on other insects, spiders, and even small birds. Their presence has wreaked havoc on the ecosystem and significantly changed the landscape. So, how did these tiny creatures have such a huge impact? Cella Wright investigates. Lesson by Cella Wright, directed by Steve West, Lazy Chief.
