If you pay attention, you don't need for anyone to tell you about Evolution. Cladograms form themselves. The vertical axis is time. Crystal clear.
But you can see the clades in nature even without access to the geologic column. Just by watching traits in the living world you automatically classify them.
The picture shows some Chelicerates (fossils, except for the scorpion). They belong to a subphylum of the phylum Arthropoda, or a phylum of the superphylum Arthropoda, according to some.
Those distinctions are not about facts, of course. Just words.
This phylum or subphylum includes horseshoe crabs, scorpions, spiders and mites.
From the marine species, only horseshoe crabs survive:
We call them "crabs" but we know they're not.
They use those tails to flip themselves back on their feet if they have been exposed. So we can make quite good deductions about some bugs in the first picture.
