The Animal Plane & Evolution?

**(Please Theravada perspective if possible)** NAMO TASSA BAGAVATO ARAHANTO SAMMA-SAMBUDDHASA (I am not fluent, forgive errors) *These are my following questions:* > - Do animals feel emotions just like us or do they feel emotions on an instinctual level only? > - What makes animals different from humans according to their planes of existence? > - How can an animal get out of their plane? Is it by working off Kamma by suffering? > - How does evolution work in terms of animals/humans cause I hear it works with Buddhism? Metta to all!
