When did Tamerlan Thorell create the genus Haplopelma?

In 1890, Tamerlan Thorell described a species of spider under the name Selenocosmia doriae. In 1892, Eugène Simon decided that this species was sufficiently different from others placed in the genus Selenocosmia to warrant a new genus, Haplopelma, with one species, Haplopelma doriae.

Which is the best description of a haplogroup?

Haplogroups are important and extremely interesting! What is a haplogroup? A haplogroup is a group of people who share a common paternal or maternal ancestor. Your haplogroup is determined by your haplotype, which is a group of alleles inherited in a direct maternal or paternal line.

Do you have a paternal or maternal haplogroup?

This means that every human has a maternal, or mtDNA haplogroup. As you now know, males inherit their paternal haplogroup from their fathers and both males and females inherit their maternal haplogroup from their mothers. The result of this is that close relatives can have different maternal and paternal haplogroups.
