Bio 2 Osborne everything up to 3/7
Kee cap (patella)
Only bone not traceable back to Tiktaalik
Devonian
360 million years ago (era w/ Tiktaalik)
Evolution
A change over time
Development
A change over time in one generation
Belief
A feeling about a topic
Transitional Fossil
A fossil that shows characteristics between two groups ex=Tiktaalick shares wrist, functional neck, and lungs with gills with fish and tetrapods.
Theory
An explanation that is "correct"
Hypothesis
An informed prediction
Selective Breeding
Breeding certain kinds of a species to get a new species. ex=humans breed dogs. Humans also breed corn to get big corn.
What part of the arm is this?
Carpals
Fossils
Evidence that something was there and alive. ex= bones or patterns in rock layers that shows change. *further layers = older rocks
What part of the leg is this?
Femur
What part of the leg is this? (smaller of 2 bones)
Fibula
What are the types of evolution?
Fossils, Embryology, DNA similarities, Biogeography, Selective Breeding, Comparative Anatomy (FED BSC)
What part of the arm is this?
Humerus
DNA similarities
Look at modern DNA and compare. *more related=higher percent of similarity ex=humans are 98 percent similar to chimps
Comparative Anatomy
Look at modern things and compare the parts. *some things could have a homologous or similar structure but have different functions. ex=tetrapods like humans and bats have the 1 bone, 2 bone, many bones pattern.
What part of the arm is this?
Metacarpals
What part of the leg is this?
Metatarsals
What part of the arm is this?
Phalanges
What part of the leg is this?
Phalanges
What part of the arm is this? (smaller bone of the "2 bones")
Radius
What part of the leg is this?
Tarsals
Embryology
The study of embryos. *more similar=more related ex=humans grow gills, webbed feet, etc because DNA from fish ancestors.
Biogeography
The study of where things occur and life and are found. ex=kangaroos are only in Australia
Tetrapods
Things w/ 4 limbs and a backbone
What part of the leg is this? (bigger of 2 bones)
Tibia
What part of the arm is this? (bigger bone of the "2 bones")
Ulna
Vertebrates
animals with backbones
