What Is On This Poster

8 facts

The facts this poster carries, so you can match it to what your kid is asking about before you buy.

Scientists sort living things into ranks: domain, kingdom, phylum, class, order, family, genus, species.
A sentence to remember the order: Dear King Philip Came Over For Good Soup.
All life falls into three domains: Bacteria, Archaea and Eukarya (Carl Woese and colleagues, 1990).
About 2.2 million species have been named; there may be about 8.7 million kinds of plants, animals, fungi and protists.
You are Homo sapiens: Eukarya, Animalia, Chordata, Mammalia, Primates, Hominidae, Homo.
A red kangaroo shares your class, Mammalia, but sits in a different order, Diprotodontia; an oak tree (genus Quercus) parts ways with you at the kingdom.
Fungi are more closely related to animals than to plants.
Carl Linnaeus set out the two-part species name in the 1750s; Homo sapiens is his name for us, from 1758.

Fits These Frames

in-frame-18x24The sample 18x24 in a standard 18x24 frame from a big-box store, the frame's brand visible on the back.

18 x 24 Inches

Fits a standard 18x24 frame, the usual size for art prints, sold at big-box stores.

Printed sizes can run a little over, so the design keeps everything that matters clear of the edge and the frame hides nothing.

in-frame-24x36The sample 24x36 in a standard 24x36 poster frame, on a wall, with a door or chair for scale.

24 x 36 Inches

The most common poster size in the US, and the one budget frames are made for. Readable from across a room.

The same margin rule: nothing important sits near the edge.
