Abstract

We submitted over 12,000 job applications, to over 4,000 job advertisements, to investigate hiring discrimination against six ethnic groups for leadership positions.

For leadership positions, applicants with English names received 26.8% of positive responses for their job applications, while applicants with non-English names received 11.3% of positive responses. This means ethnic minorities received 57.4% fewer positive responses than applicants with English names for leadership positions despite identical resumes.

For non-leadership positions, applicants with English names received 21.2% of positive responses for their job applications, while applicants with non-English names received 11.6% of positive responses. This means ethnic minorities received 45.3% fewer positive responses for non-leadership positions despite identical resumes.

Ethnic discrimination for leadership positions was even more pronounced when the advertised job required customer contact.

A rare, half-billion-year-old fossil gives us a clue to how a bizarre marine invertebrate can possibly be related to humans. In a study published on July 6 in the journal Nature Communications, Harvard University researchers identified a prehistoric specimen in a collection at the Natural History Museum of Utah as a tunicate, or sea squirt. The preserved invertebrate, which was originally discovered in the rugged, desert-like landscape of the House Range in western Utah, can be used to understand evolution mysteries that go way back to the Cambrian explosion.

“There are essentially no tunicate fossils in the entire fossil record. They’ve got a 520- to 540-million year-long gap,” says Karma Nanglu, an invertebrate paleontologist at Harvard. “This fossil isthe first soft-tissue tunicate in, we would argue, the entire fossil record.”

“This study was undertaken as part of a broader research looking at the interplay between early social complexity and gender inequalities,” study co-author and University of Seville prehistorian Leonardo García Sanjuán tells PopSci. “As part of this research, it became obvious that there is a serious problem in the identification of biological sex in prehistoric skeletons, which are often found in a poor state of preservation.”

Now redubbed the “Ivory Lady,” this woman’s tomb was first discovered in 2008 in Valencia on Spain’s southeastern coast. The find dates back to the Copper Age, when the metal was used for construction, agriculture, and even creating engravings of owls that may have been toys. The grave is also a rare example of single occupancy burial at the time and the tomb was filled with the largest collection of valuable and rare items in the region. These treasures include high-quality flint, ostrich eggshell amber, a rock crystal dagger, and ivory tusks.

All of these trinkets and single tomb initially indicated that the remains must belong to a prominent male, but peptides and DNA don’t lie.
