Can the following sentences:
-'Many animal species, including birds and fish, experience yawning' Be changed to 'Almost all vertebrate animals, including mammals, birds, reptiles, amphibians, and even fish, experience yawning.' -'A yawn is a reflex consisting of the simultaneous inhalation of air and the stretching of the eardrums, followed by an exhalation of breath.' Be changed to: 'A yawn is a reflex lasting 4-7 seconds, and is characterized by a long inspiratory phase with gradual mouth gaping, followed by a brief climax (or acme) with muscle stretching, and a rapid expiratory phase with muscle relaxation. [1][2] For fsh and birds, this is described as gradual mouth gaping, staying open for at least 3 s and subsequently a rapid closure of the mouth. [3]
- This is a more accurate defenition of a yawn and animals that perform yawning. Stretching the eardrums is only a small part of the yawn and refers to one specific hypothesis (middle ear clearing). This is considered a side-effect by many scientists in the field of yawning, thus I would not state it in the defenition.

"Relation to empathy" citations.
There were a few statements in the section about empathy that weren't sourced, particularly related to whether autistic people struggle with empathy.
I added citation needed tags, but I'm not an experienced Wikipedian so feel free to remove them if they aren't relevant.
Also, I feel like it's unclear what kind of empathy is being discussed. Squoop (talk) 11:17, 18 August 2023 (UTC)
