The bird pauses before deciding whether or not to land beside food, looking around carefully before making its decision. While this takes only one second, it means far more than just instinct taking over. Such a brief period implies some form of evaluation, something scientists now link to different levels of consciousness among animals.
For a long time, consciousness was thought to be unique to humans; however, science has evolved from such beliefs. According to research conducted at Frontiers in Psychology, consciousness might have evolved gradually as a result of growing brain complexity in ancient vertebrates.
Consciousness did not emerge overnight but rather gave organisms the ability to assess both their inner state and stimuli outside of them.

How is awareness widely distributed?
"Conscious-like activities are no longer unique to mammals when it comes to the discussion in science." As noted in articles appearing in ScienceDaily, birds exhibit selective attention and behavioral flexibility, implying the use of sophisticated cognitive functions despite their different brain organization.
From a philosophical and biological perspective, the Stanford Encyclopedia of Philosophy provides insights that there may be various paths of evolution leading to the development of some sort of consciousness in different animals. In other words, it is possible that awareness has evolved not only once but separately in different species.

With such information, more studies could look into various species, such as those found in the invertebrate kingdom.
Consciousness can be used as a tool for survival
The importance of consciousness lies in its influence on the way animals behave. According to a review article in Neuroscience and Biobehavioral Reviews, early types of consciousness were associated with emotional regulation, enabling organisms to assess dangers and rewards.
This form of self-reflection enhances decision-making, enabling living creatures to modify their behavior in response to previous experiences instead of sticking to certain stereotypes.
Though not necessarily correlated with direct evolutionary advantages, such flexibility provides some indirect advantages in a changing environment. Consciousness, according to this hypothesis, is not a static quality but a continuum, affecting the way animals relate to their environment in complex ways.
