Darwin's theory is able to be used in real life today. Not only does society use survival of the fittest schools teach his theory of evolution. Society allows those that are better off or fitter in society to get ahead due t the person fitness in society. Along with those Darwin's theories are used in life today and in the past.

1. What do hox genes control? They turn on and off other genes in the head to tail development of embryos.

2. What were Lamarck’s ideas about evolution? Traits acquired from a person's lifetime could be passed down to its offspring through use and disuse of body structures.

3. What does natural selection directly act on? Phenotype such as an organism characteristics

4. What shape will a graph have if it represents a polygenic trait? Bell shaped curve

* Survival of the fittest is Darwins law.
*  Darwin's ideas about Natural Selection explains that by talking about how some animals are distantly related to common ancestors and those animals have evolved differently from each other due to having common ancestors.
*  genetic drift is random different ancestors pass different genes down.
* Darwin's theory of natural selection works in life today. Survival of the fittest. If your unfit you wont make it. It acts on all species in an environment.

1. Evolution - The process of change over time.

2. hox genes- a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body.

3. Charles Darwin  - Suggested the theory of evolution/natural selection.

4. Uniformitarianism  - The idea that the geologic processes we see today are the same ones that have shaped the Earth for many years.

5. Jean-Baptiste Lamarck  Proposed hypothesis that organisms could change during their lifetime by selectively using or not using certain traits.

6. Acquired characteristics  Traits altered by an individual organism during its life

7. Artificial selection  A process in which nature provides the variations, and humans select those they find useful

8. Adaptation  Any heritable characteristic that increases an organism's ability to survive and reproduce in an environment

9. Fitness  Describes how well an organism can survive and reproduce into its environment

10. Natural selection-the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
