First of all, evolutionists need to stop stating anything from their work as fact, because none of it is proven.
But my specific example that maybe one of you Darwin-suckers can help me with is this:
Why do they say that parrots or peacocks have their colorful plumage and have noisy calls because they evolved that way to attract mates. Yet, sparrows, grackles and other dull, boring birds get laid all the time, even without blue or orange feathers.
And conversely, why is it said that sparrows, grackles and otherh dull brownish birds have such colors to avoid prey. Meanwhile, these parrots who need flashy colors to get laid are defeating the purpose of all this fornication by being easy to spot by predators.
Pure nonsense.

My teacher either doesnt word her questions right, or I'm just not getting it..

She asks:
What is an autosome? How many autosomes in a human body cell? A human gamete?

My Answer:
An autosome is a chromosome that is not involved in sex determination. There are 22 pairs of autosomes in a human cell, and 1 pair of gametes.

**Could someone tell me if this is what she wanted to hear?
---------------------
Another question is:
What is a sex chromosome? How many sex chromosomes in a human body cell? A human gamete?

My answer:
A sex chromosome is the X or Y chromosome that determines the sex of a person...(didnt finish)

**If I could get some help on that one too, it would be great!
