evolution of behaviour Flashcards
what is the definition of evolution?
the process whereby a species’ heritable characteristics change over many generations
what is meant by development?
the changes an animal undergoes during its lifetime
how can a stable environment influence an animal’s behaviour?
they become perfectly adapted to the environment
how can the environment cause an animal to change its behaviour?
- unexpected change in climate (no migration)
- competition with other animals for mates, food and territory (increased aggression)
how is the behaviour of domesticated animals influenced by the environment?
mostly through operant conditioning (electric fences, learn not to go near it)
what is innate/instinctive behaviour?
a behaviour that is inherited or “hard wired” and is not learnt or taught
why does animal behaviour evolve?
to suit their environment and increase their genetic fitness
