What is evolution?
The theory the old living species are the modified Descendants of earlier species
We all share common Ancestor
Therefore all species are related via a past tree of life
Just a Theory
What’s the evidence (4)
Anatomy - By looking at the anatomy of different species, we can find similarities or evidence that shows us that they may have been related a long time ago
Biochem - the chemicals that are used in metabolism. By examining the chemical makeup of different living things, We can see how closely they are related.
ex. Organisms use DNAs as their genetic makeup
development - comparisons of development as a structural evidence for evolution. Like looking at embryos, like how all vertebrate embryos have gill slits and a tail during early development.
DNA & Genes - DNA and gene similarities compared to other species
Why are scientific names powerful
Because the species will always be identified by that name
what is binomial classification?
A two word name for each organism
The first word is the genus, begins with a capital
The second word is is the species, No capital
Genus and species are always written in italics or underlined
Types of cells (2)
Prokaryote versus eukaryote
P - Organisms contain no nucleus or other membrane-bound organelles
