Why are we more closely related to fungi than plants?

4/30/2025
All living things on Earth are related. To help keep track of how close those relationships are, scientists organize life on Earth into groups using a system called taxonomy. Sometimes, taxonomy can be surprising – like, did you know that humans are more closely related to mushrooms and other fungi than we are to plants? How does that work? We asked microbiologist Christine Salomon to help us find the answer. Got a question that’s in a class by itself? Send it to us at BrainsOn.org/contact, and we’ll find an answer that’ll really grow on you.

Do lizards smell with their tongues?

4/23/2025
The sense of smell is so powerful. Without it, we couldn’t sniff out freshly-baked muffins, stinky garbage, or smoky campfires. Some animals use their noses, others use antennae or even their feet to smell. But what about lizards? They have nostrils, but do they use them to smell? We asked lizard researcher Laura Kojima to help us answer this question. Got a question that you need to make scents of? Send it to us at BrainsOn.org/contact, and we’ll help you sniff it out.
