Card 1

Question: What early ability of newborn infants suggests humans may have used melody before words?

Answer: Newborns can recognize and prefer the intonation of their mother’s voice and their mother’s language, suggesting early use of melody to express themse

Card 2

Question: What evidence suggests other animals also produce songs, questioning uniqueness of human melodic origins?

Answer: Many creatures, such as songbirds and humpback whales, produce songs, indicating melody alone is not unique to humans.

Card 3

Question: What is the 'yo-he-ho' or Social Interaction Source theory for language origins?

Answer: Jespersen’s 'yo-he-ho' theory proposes sounds arose from vocalizations used to coordinate group physical effort (e.g., grunts and curses during cooper

Card 4

Question: Why is the Social Interaction Source appealing for explaining language origins?

Answer: Because it places language development in a social context: early humans lived in groups that required communication to maintain social organization a

Card 5

Question: What limitation of the Social Interaction Source is noted regarding explaining speech origins?

Answer: Although primates use grunts and social calls in groups, they did not develop speech, so the theory doesn’t explain why humans alone evolved speech ca

Card 6

Question: How did bipedalism potentially affect human speech according to the Physical Adaptation Source?

Answer: Bipedalism decoupled breathing rhythm from walking, allowing longer exhalations and short inhalations, supporting extended articulated speech (about 9

Card 7

Question: What breathing pattern is associated with human speech production?

Answer: Human speaking breathing is approximately 90% exhalation with only about 10% of time for quick inhalations.

Card 8

Question: What fossil evidence suggests some speech-like sound distinctions existed in ancient humans?

Answer: A reconstructed Neanderthal vocal tract (~60,000 years ago) suggests some consonant-like sound distinctions were possible.

Card 9

Question: Around when do fossilized skeletal features resembling modern humans start to appear, relevant to speech capability?

Answer: Around 35,000 years ago, skeletal features that resemble those of modern humans begin to appear.

Card 10

Question: What general approach does the Physical Adaptation Source take to explain origins of speech?

Answer: It looks at physical features of humans—especially anatomical changes (like bipedalism and vocal tract structure)—that may have supported the producti
