Which type of evidence for evolution is most accurate in determining evolutionary relationships morphology or biochemical/molecu

Biology

gregori [183]3 years ago
4 0

Answer:

Evidence for evolution comes from many different areas of biology:

Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).

Molecular biology. DNA and the genetic code reflect the shared ancestry of life. DNA comparisons can show how related species are.

Biogeography. The global distribution of organisms and the unique features of island species reflect evolution and geological change.

Fossils. Fossils document the existence of now-extinct past species that are related to present-day species.

Direct observation. We can directly observe small-scale evolution in organisms with short lifecycles (e.g., pesticide-resistant insects).

________ are neurons in the brain's visual system that respond to particular features of a stimulus.
forsale [732]

Answer:

The cells of the visual cortex are neurons in the brain's visual system that respond to particular features of a stimulus.

Explanation:

These neurons respond to stimuli presented to both eyes. Simple cells receive innervation directly from thalamic cells and respond to light stimuli with defined orientation and with specific configuration and location in the visual field. Complex cells also respond to the orientation parameter.  

These cells trigger action potentials when the visual stimulus appears within their receptive field.
