(22 cards)
Other evidence for macroevolution is the _________ record.
Fossil
The fossil record includes the remains of dead organisms in ___________ rock; organisms in lower rock layers tend to be _______, while organisms in higher rock layers tend to be more ________-did upper layer organisms evolve from lower layer ones?
Sedimentary, simpler, complex
The fossil record also includes ___________ species.
Transitional
An example of transitional species is the evolution of _________; fish—>__________—>reptiles—>birds or mammals.
Vertebrates, amphibians
If macroevolution happened, there should have been __________ of transitional species (example: many species between a fish and an amphibian).
Millions
Some use the lack of these transitional species as an argument ________ evolution.
Against
Other evidence for macroevolution are ________, similarities between organisms that provide evidence that the organisms may have evolved from a common ancestor (like botanan curus and species Z).
Homologies
An example of homologies are similarities in _______ structure.
Body
Homologous structures are similar structures that related species may have ________ from a common ancestor.
Inherited
_______ of vertebrates contain same bones in same position, but bones with different ______; evolves from a common ancestor?
Limbs, shapes
Vistigial organs are organs that are so reduced in size or function that they are merely ________ of similar organs in tiger species; does this show a common ancestor?
Traces
An example of a vistigial organ are boas and pythons have tiny _______ that are all that remains of what once could have been ______?
Bones, legs
An example of a vistigial organ is human’s miniature _________ at the end of the spine-evolved from a ______?
Tailbones, tail
An example of a vistigial organ is a human’s _______-from a common ancestor where it had a purpose?
Appendix
Homologies can can also be similarities in early ___________.
Development
________ of vertebrates (fish, amphibians, reptiles, mammals, birds) look similar? This shows that all share the same ______ for early body development, showing they might come from a common ancestor.
Embryos, genes
Recently, Ernst Haeckel, the discoverer of the similarly of embryos of vertebrates was proven to have ________ be drawings to make the embryos look more ________ than they really do.
Forged, similar
Similarities in early development is no longer _______ now to support evolution (although for some reason it is still taught in text books).
Used
Homologies can also be similarities in chemical __________ (loving things are made of the same stuff).
Compounds
All living things have ______ and _____ to store information for making proteins, and DNA _________ the same in all.
DNA, RNA, replicates
Many living things share similar DNA ________ (such as Fission Yeast); the more similar the DNA sequences the more ________ related the species.
Sequences, closely
Living things use ______ for energy storage and contain many similar _________.
ATP, proteins
