Scientists have discovered the oldest-known fossil of a pine tree.
The charred pine twigs date back 140 million years to a time when fires raged across large tracts of land.
Pine trees now dominate the forests of the Northern Hemisphere.
The research suggests the tree’s evolution was shaped in the fiery landscape of the Cretaceous, where oxygen levels were much higher than today, fuelling intense and frequent wildfires.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
