That is incorrect. Evolutionary pressure permits the survival of species which are *sufficiently adequate*, as opposed to only the “fittest” species.

Also, to be consistent with reality, if one makes an argument in favor of access to the tools of molecular biology for teenagers, as was done by the speaker, one should not object to making the nuclear weapon components to be universally accessible. Such argument is not accepted to any informed person. Proponents of “synthetic biology” can make their arguments today because no biological weapons have yet been used to the same degree as nuclear weapons.

The concept of rebuilding nature with “tools” is self-inconsistent and dangerous to all life forms, including venture capitalists of financiers of this proposed non-sense.

The anticipation, or perhaps the misguided hope that envisions humans (or scientists) to be able to control “synthesized life” is based on the misconception about what it takes to create life.

The proponents of synthetic biology believe that there is a utility function to be derived by “engineering life”. Perhaps, but they fail to disclose that this could only be efficiently and economically accomplished by means of selection, rather than by screening for such a function. While screening for a new utility function poses little risk, selecting for a new utility function from a library of “synthetic” individual genetic variations is dangerous. The intrinsic difference between the processes of selection and screening would result in only two possible outcomes.

Should the screening method be used, one cannot expect to derive any sufficiently justifiable new utility function because we do not yet have sufficient information to design life rationally.

In contrast, the termination of many current species, including possibly humans is virtually predictable should the selection method be used to circumvent human inability to design life rationally. Once a library of engineered organisms, rather than an individual “new” species would be introduced into an ecosystem in an assisted attempt to select for a new utility function, the unfair survival advantage of the “new creation” is virtually guaranteed. Hence, only the fittest survive.

One needs to re-think that value proposition of “synthetic biology”. People of means, with all thy getting get understanding.
