Give one example of a pressure that would cause natural selection to take place.
Resource availability
slight differences in an inherited trait
Variation
What is Ms. Collins favorite animal?

Fossils!
Define selective breeding.
Human involvement selecting for certain desired traits.
An organisms ability to pass its genetic material on to its offspring is _______
This means they are able to drive natural selection!
Fitness
Survival of the fittest
Inherited trait that increases an organisms chance of survival.
Adaptation

DNA
Positives of selective breeding
Happens quickly and can benefit humans especially when it comes to food.
What are the 3 requirements for natural selection?
1. Traits can be passed down
2. Variation in the population
3. competition or pressure
Homologous Structure
physical features in different species that share a common evolutionary ancestor, even if they serve different functions
What is Ms. Collins favorite dinosour?
Velociraptor
Did humans evolve from monkeys?
NO we share a common ancestor.
Drawbacks of selective breeding
Reduces the variation quickly
inbreeding making organisms prone to disease and genetic defects.
