DNA, evolution, taxonomy

A double helix, complimentary pairing of adjacent strands

Deoxyribonucleicacid

Adenine and Thymine, Guanine and Cytosine. It’s connected to the backbone of the DNA which is a sugar-phosphate backbone.

when there are changes in the expressions of a gene or chromosome that affects the proteins produced as a result

also known as “survival of the fittest”. Organisms with genes more fit for the environment are more likely to survive and reproduce

changes in the genetic make-up of a smaller population due to unplanned coincidences

Change in the population allele frequency due to migration

the ability to let organisms pick their own mates to reproduce with through physical or behavioral traits

a way to keep 2 species isolated and apart

the theory that evolutionary change goes in short bursts rather than a steady constant path

organisms that share similar features or structures in their limbs but different functions

same function different structure

a direct piece of evidence to show evolutionary change through time, adaptive radiations and extinction

the theory that change goes at a steady and slow rate

the study of the development of organisms during the early stages of life

organs/structures that lost its function/purpose over the course of evolution

the remains of an organism used as direct evidence for evolutionary change

Charles Darwin. He used finches to study how they would adapt to different environments

organisms with more similar DNA and protein compositions are more likely to be related

domains: bacteria, eukarya, archaea kingdoms: plantae, animalia, fungi, protista, eubacteria, aechaebacteria

vertebrates are organisms with back bones or spines, invertebrates are organism who don’t have them

unicellular, no membrane bound organelles, no defined nucleus, very small, prokaryotic organelles with a flagellum lack the 9+2 pattern

multicellular, has membrane bound organelles, has defined nucleus

the theory that all organisms evolve and diverge through a common ancestor
