Do you see the problem?

We are creating a reduction in diversity in the genetic pool

1. All of life
2. Humans
3. Human personalities

We are moving towards "blandness".

This is scary because earth conditions change slightly even over just 100's of years.

Do you see what i mean? Lets see how well you can guess my thoughts and articulate them.

Cheers!

When Neutral theroy says that Genotypic changes which occur most of them will not produce any phenotypic changes. So By only survival of fittest & natural selection & hypothitical isolated environment can evalution occur

Like in the movie gattaca. They look at your intelligence and any defects like a bad heart. Employers currently use: psychological tests, drug tests, credit check, background check. (this is for example used by PRiVATE banks)

They could also use the drug test without letting you know they did it.

You are an epidemiologist charged with investigating and putting a stop to repeated outbreaks of giardiasis in an old, run-down, urban public school. Discuss the hypotheses you would form and the investigation that you would undertake.

Thank-you for taking the time to read this.

I have a picture of a form of multi-cellular algae. My first guess was brown algae, but I'm second guessing myself. It looks like a leafy-plant, and it has roots (looks like the roots of a plant). The question is:
Is this brown algae? If not, what type of algae is it?
What is the function of the roots on the algae?
Are these even roots? (Could be calling them by the wrong name)

-Thanks a bunch!
