How does evolution really work?

We watched this video in both honors and CP classes and journaled in our notebooks on the following two questions (for a notebook stamp):

1. What are the four parts of the theory of natural selection?

2. How does overproduction of offspring effect competition?

3. What does survival of the fittest mean?

4. What does differential survival and reproduction mean?

Chromosomes and Cell Reproduction 3/30/17

Today in class, we built and drew models of chromosomes, we also described them using terms like: chromatid, centromere, DNA, and histones. We took notes and reviewed the image below. Then, we watched a video on genetic variability. We answered the following questions in our notebooks: “How do sexual and asexual reproduction compare? What are the advantages and disadvantages to both?” The Red Queen Hypothesis was mentioned in the video. Think about how that relates to evolution and genetic diversity.untitled
