EVOLUTION Flashcards
Refers to change in the characteristics of an organisms overtime
Evolution
Are the remain of organisms that have been preserved in different ways
Fossils records
Greek word of petrification
Petra
Happen when the minerals in the underground are absorbed by the tissues of the dead of organisms
Petrification
Lived in Luzon approximately 50,000-67,000 years ago
Homo luzonensis
Fossils of homo lunensis are found in
Callao cave in Cagayan valley
Is a scientist who studies fossils
Paleontologist
Provides support to evolution by comparing the body structure
Anatomical evidence
Anatomical evidence is divided into
Homologous ang vestigial
Shows similarities in the body structure of different organisms with different function
Homologous evidence
organs are parts of organisms that have been reduced size significantly overtime
Vestigial evidence
Similarities in early development are also used as evidence for evolution. Embryonic stages of some closely related organisms are similar
Embryological evidence
Found in side of the throat and are present during their embryonic stage
Pharyngeal slits
Study of molecular basis of and gene expression.
Molecular biology
Method that used to compare proteins. Determines sequence of ammjno acid in a polypeptide
Amino acid sequencing
Evolutionary changes can be measured using
Molecular clock
They introduced the concept of molecular clock in 1960
Linus Pauling and emile zuckerlandl
It measures number of changes or mutation that occur into the gene sequence
Molecular clock
Predicted that the population of human will grow faster than the amount of space and food need to survive
Thomas malthus
