Smithsonian explains how the genetic differences between different snakes can show the landscape of South America.
Neotropical rattlesnakes are found in dry, arid parts of South America and small savanna pockets in the Amazon. Many of these snake populations are discontinuous — or separated from one another by wet rainforest habitat. Although these populations are all part of the same species, they have small, but noticeable genetic differences. These differences can signal when and where populations stopped interbreeding and became geographically isolated. But it’s difficult to picture how and when these gradual changes happened.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
