Adaptation
In adaptation is a characteristic that helps an organism survive and reproduce in its environment
Evolution
The basic "evolution" is to "change" over time
Fossils
Fossils are preserved remains of once living things
Genes
Genes are the characteristics an individual has that were inherited from their parent
Biological Engineering
Engineering in a specific organism to give it a certain trait
Biological Evolution
Biological evolution means "the change of characteristics of a group of organisms over many generations
Natural Selection
The process in by which individuals that are better adapted to their environment are more likely to survive
Homologous Structures
Homologous structures are similar in structure but different in function
Scientific Theory
Based on reasoning and evidence to explain some aspect of nature
Species
A group of organisms that can mate with one another to produce fertile offspring
Evolutionary Tree
A diagram that shows how scientists think different groups of organisms are related
Embryology
Embryo development shows how organisms have similar embryos that develop into different adults
Common Decent
Sharing a same ancestry
Vestigial Structure
Vestigial structures are remnants of organs or structures that had a function in early ancestry
Scientific Law
A generalization, principal, or pattern in nature
Physical Adaptation
Physical adaptations are body structures that allow an animal to find and consume food, defend itself, and to reproduce its species
Behavioral Adaptation
Behavioral adaptations are actions that help an organism survive in its enviormrnt
Three Main Tenets of Science
#1 Science cannot answer all questions #2 All knowledge is changing in science#3 Science cannot provide absolute proof
Why Do Adaptations Help Organisms Survive?
Adaptations are the result of different environments, habitats, and ecosystems
Decent With Modification and Evidence
All organisms came from the same ancestry (Evolutionary Tree)
How Species Change During the Process of Natural Selection
Struggle to Survive -A natural environment does not have enough food, water, and space to support
Natural Selection
#1 Overproduction#2 Genetic Variation #3 Struggle to Survive #4 Successful Reproduction #5 Environment Change #6 Genes
Sexual VS. Asexual Reproduction Differences
Sexual-Environment Change -No Build up of Bad Genes-Variation in the Population Asexual-Pass on Beneficial Genes -Only need one parent -Produce twice as many offspring (All Female)
Difference Between a Law and Theory
Theory-Says WHY something happens in natureLaw-Is HOW something will happen
Evidence for Evolution
#1 Fossil Evidence #2 Homologous Structures#3 Vestigial Structures #4 Observed Evolution #5 Embryology (Ontology)#6 Genetic Similarity
