“You are special” But not as special as you think.
CB 1.3 What is life?
2. They must have metabolism. 3. They must respond to the environment.
Living organisms must fit all of the following criteria: (modified from Campbell “Biology”) 1. They must have organization. 2. They must have metabolism. 3. They must respond to the environment. 4. They must be able to reproduce themselves.
Can we create “artificial” life? What would it be like? Can something with these traits be considered not alive?
Creation of a bacterial cell controlled by a chemically synthesized genome.C Venter et al Science 329: 52-56. Synthetic DNA put into a M. capricolum recipient cell...The new cell has the characteristics of M. mycoides Synthesized DNA based onM. mycoides “The new cells have expected ... properties and are capable of continuous self-replication.”
...even the simplest forms of life have unpredictable, emergent properties. These properties are often useful and we want to control them, but their unpredictability presents a conundrum for traditional engineering. We must develop and perfect methods for engineering emergence.-Mark Bedau Professor of philosophy and humanities, Reed College, Oregon Life after the synthetic cell Nature 465: 422–424 (27 May 2010)
Venter's achievement would seem to extinguish the argument that life requires a special force or power to exist. In my view, this makes it one of the most important scientific achievements in the history of mankind.-Arthur Caplan Professor of bioethics, University of Pennsylvania Life after the synthetic cell Nature 465: 422–424 (27 May 2010)

Several species can recognize self in mirror by dot test or actions in front of mirror. They do not see mirror image as other, but self.
Is a sense of self necessary for feelings? Should our interactions with animals depend on their self-awareness? Is self-awareness necessary for feeling pain, fear, etc?

Maintaining a complex society requires culture and language.
The complexity of our societies is reflected in human culture… Do other animals have culture?
