Some scientists think the first migrants to the Americas came by crossing a land bridge.
Most scientists believe the first migrants came to North America from Asia.
Explanation:
In the past century there has been a consensus about the migration of people to the Americas. It was commonly accepted that the first humans in the Americas came at the end of the last Ice Age. The hypothesis says that they came by a land bridge that existed between North America and Eurasia, and that their origin was from what is now Siberia, or rather from central and eastern North Asia. This has been and still is the most accepted hypothesis.
In the past couple of decades though the view on this hypothesis started to change. Lot of new evidence emerged that suggest that this hypothesis is flawed so more and more scientist are not supporting it.
There has been new sites where remains of human activities have been found and they predate what was suggested by tens of thousands of years. The genetic studies are suggesting that there are groups of people that originated from Polynesia and from Northern Europe. In Mesoamerica and in the Amazon there are multiple groups of people that have Polynesia genes, while some Native Americans in the eastern part of North America have European genes. This means that people migrated not just from Asia, but also from Northern Europe (by a boat or through a land bridge), and by a boat though the Pacific Ocean.

Answer:
Both breeches and pantaloons were worn during the 1810s. Breeches extended to the knee where they were fastened with buttons and a buckle or tie (Fig. 1); pantaloons, which had originated in the 1790s, were very tightly-fitted and longer, extending to the calf or ankle where they fastened with ties or buttons (Fig. 4)(Byrde 93; Johnston 14). Either could be worn during the day, but breeches were the proper evening attire with white stockings and evening pumps (Fig. 5). For daywear, both were frequently worn with tall boots, a favorite fashion of early nineteenth century menswear (le Bourhis 112). It was particularly in vogue to wear pantaloons tucked into “hessian” boots, defined by heart-shaped tops and tassels (Laver 160). Named for the Hessian mercenary soldiers from Germany, these boots and clinging pantaloons, which displayed a man’s leg muscles to great effect, lent a martial glamour to civilian dress (Ashelford 186; Johnston 14). The man in figure 1 of the Womenswear section sports pantaloons and hessians.
