Is it normal that your vids don’t work?
Hi Biologist. The presentation link was broken and has now been fixed. Thanks for letting me know. Videos within the presentations are actually links to original animations andvideos – just click and it should bring you there.
The YouTube videos above work fine – check to make sure you are allowed access to YouTube where you are.
Steve.
