Questions with All Actual Verified
Answers 2025-2026 Updated.
Ray - Answer no interbreeding
linnaeus - Answer evolutionary change promotes the formation of new species
buffon - Answer life forms are not fixed
malthus - Answer only part of the pop survives/reproduces
uniformitarianism - Answer changes in the earth are directly caused by recurring events
Lamarck's theory - Answer individuals can acquire traits during their lifetime and pass them
onto their offspring
ex. giraffes cannot stretch their neck to reach leaves, but those with longer necks have less
comp for resources so they are more likely to survive and reproduce
what evidence did darwin collect on the Galapagos - Answer birds of different islands had
different size beaks for specialized feeding strategies
fossil records - Answer show a change over time, younger orgs closer to the surface
ex. fish to terrestrial orgs
biogeography - Answer studies the geographical distribution of extinct and modern orgs
ex. same animals on different continents
convergent evolution - Answer two species from different lineages show similar
characteristics due to similar environments
ex. ant eater nose and other orgs not from the same lineage
selective breeding - Answer modified traits in domesticated species
ex. dogs
homologies - Answer fundamental similarity due to descent from a common ancestor
, anatomical homology - Answer similar body structures among different species from a
common ancestor
ex. limb bones of vertebrates
developmental homology - Answer similarities in the development of embryos between
different species that share a common ancestor
ex. human embryo has gills
molecular homology - Answer similar DNA (amino acid sequences) among different species
from a common ancestor
ex. hox genes
homologous traits - Answer features that are inherited from a common ancestor
analogous traits - Answer arise when groups independently adapt to similar environments in
similar ways
fitness - Answer Ability of an organism to survive and reproduce in its environment
1. all orgs produce too many offspring
2. not all offspring reproduce
3. natural resources are limited
4. individuals of a pop vary
5. many variations are heritable (passed down) - Answer Darwin's theory of descent
heritable variation - Answer differences that are passed on from parent to offspring
homologous genes - Answer two or more genes derived from the same ancestral gene
ortholog - Answer genes in different species that evolved from a common ancestral gene by
speciation
paralogs - Answer homologous genes within a single species
exon shuffling - Answer The variation in the patterns by which RNA may produce diverse sets
of exons from a single gene.
