Sizes also changed in time- the tiny seed beads are of a later date.
This is one of those myth conceptions that just won't die. While it's true that seed beads became more popular after 1840, the facts show via trade lists as well as archeological evidence that small beads were known and used prior to the later periods, on some pieces in particular some by the Crow and Comanche, use a mix of sizes.
Below is some info including dug beads from 1800 measuring as small as 20/0.
My own interest lies with the beads sewn on as decoration - i.e seed and pound (often/mistakenly called pony beads - a 20th Century historians description):
Info on these types:
1) A treatise on seed beads in the "Northwest" (they were used earlier than most think - all depends on time and place - the Metis were using them in the Great Lakes area by the late 1700's): http://www.northwestjournal.ca/IV2.htm
2) Museum of the Fur Trade Quarterly Vol 34, #4, Winter 1998 a sample pic of some excavated beads from the cover:
3) Book of Buckskinning 8: Beadwork in the American West pre-1850 by Allen Chronister
4) Original Fur Trade lists - include "white" hearts, pound, seed, and more styles in several colors. Pound/seed: in white and blue - varying shades from sky, to grey, to navy being the most common in the earliest days: http://www.xmission.com/~drudy/mtman/bizrecs.html

40 Wampum Hairpipes
Note that by the late 1830's the number of colors and styles had increased. Also note the continued use of wampum, both for beads and hair pipes. Whether the wampum is the "real McCoy" or the glass imitation type it is not clear - most likely the latter? According to R. F. Kurz who worked as clerk at Ft. Union circa 1851, beadwork had almost completely supplanted quillwork, which had still been quite common in the mid-1830's (see Bodmer and Catlin for examples of western quillwork mixed with beadwork.)
5) the book "Arts of Diplomacy: Lewis & Clark's Indian Collection" shows some excellent examples of pr-1840 beadwork
FWIW - pound beads go way back:
these are from the wreck of LaSalle's ship off Texas in the late 1600's:
and here's a selection of pound beads from the Great Lakes area (circa late 1700's) it's included in the book "Where Two Worlds Meet":
