Carnivorous Plants: The Evolutionary Success Of The ‘Sundews’ (Video)

Covered in long, sticky tentacles, the Sundew is a predatory plant that looks like it’s from another planet.

Sundews are “flypaper” plants that trap prey in sticky hairs on their leaves. They make up one of the largest groups of carnivorous plants. Long tentacles protrude from their leaves, each with a sticky gland at the tip. These droplets look like dew glistening in the sun, thus their name.

Drosera, commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. These members of the family Droseraceae lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces.

Wildlife: The Uncertain Origins And Evolution Of The Turtle (Video)

Turtle evolution has caused many problems for scientists over the years due to multiple fossil discoveries seeming to contradict each other with different turtle features evolving independently on different turtle ancestors. However, although there is still work to be done this video sets out to explain what is known so far.

Why is the world the way it is? How did we get here? Does everything happen for a reason or are some things left to chance? Philosophers and theologians have pondered these questions for millennia, but startling scientific discoveries over the past half century are revealing that we live in a world driven by chance.

Sean B. Carroll is an award-winning scientist, writer, educator, and film producer. He is Vice President for Science Education at the Howard Hughes Medical Institute and the Balo-Simon Chair of Biology at the University of Maryland. His books include The Serengeti Rules (Princeton), Brave Genius, and Remarkable Creatures, which was a finalist for the National Book Award. He lives in Chevy Chase, Maryland. This talk and Q&A was recorded by the Royal Institution on 6 October 2020.

Video Interviews: “The Biological Universe” Author Wallace Arthur

Are we alone in the Universe, or are there other life-forms ‘out there’? Recent discoveries of planets beyond the solar system (more than 4000 of them) suggest that the question is not ‘whether?’ but ‘where?’. This book enables general readers to understand current endeavours to answer this question and the related one of ‘what kind?’
