What does it mean to say that the fossils record suggest that evolution occurs among living things?

The fossil record reveals relatively gradual changes in species over time. For example, the earliest horses had three toes and a curved spine, and were quite small. Over millions of years the outer toes migrated up the leg and fused with the leg bone. The teeth changed from browsing on leaves and twigs like those of deer to grazing on grass, more like the teeth of cattle.

According to evolution evolution generally occurs when?
Evolution occurs when life forms reproduce with genetic variation of inherited traits, within an environment with a limited carrying capacity (which is basically all environments). In other words, evolution happens where life as we know it exists.
What part of the cell theory did Lynn margulis contribute to?
She concluded that some organelles found in eukaryotes were once free-living prokaryotes.
Give an example of a chemical change that occurs in your living environment and a chemical change that occurs in your non living environment?
Living: photosynthesis, moldy cheese Non-living: Burning wood, carving wood
What conditions make impression fossils form?
The best preservation and fossilization of fossils occurs in calm,aquatic environment.Exceptional preservation also occurs in fine-grained sediments in absence of oxygen.Both this environmental conditions allow easier formation of impression of trapped fossil plant of animal.Impression mainly form from fossils plants and animals that are later decomposed leaving their image shape on the country rock at the time.CONDITIONSWet conditionfine grained country rockaerobic condition that favor decomposition of the fossils leaving behind impression
What is the ability of an organism to change internally and externally in relation to its environment?
The process where organisms evolve through time is called evolution. This natural phenomenon occurs as a result of changes in the environment.
The smallest unit in which evolution occurs is?
The smallest unit in which evolution occurs is a population.
How the fossils record supports the theory of punctuated equilibrium?
the fossils show massive change at one time (for instance the Grand Canyon; this massive change occurs usually from significant weather/environmental events) , and during the periods between the significant changes not much evolution (changes in genetic expression/genes) occurs.
Why are fossils of intermediate life forms likely to be rare if the pattern of punctuated equilibrium explains how evolution occurs?
Intermediate species forms, yes. A the taxa level, no. Still, not all taxa evidence is supportive of punctuation and stasis. Punctuated equilibrium is only one explanation of how evolution occurs in some species, not all species. The little shellies evidence gradualist processes very well.

What three items do evolutionists disagree about?
One is that evolution occurs gradually and consistently.The other is that evolution occurs as a result of competition for 'niches'
What part of the cell theory did Lynn margulis contribute to?
She concluded that some organelles found in eukaryotes were once free-living prokaryotes.
Is evolution closely related to DNA?
Yes; changes in DNA are the vehicle by which evolution occurs.
Occurs when species that were similar become increasingly distinct?
Divergent evolution:)
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
What type of reaction occurs to fossils under pressure in the sediment?
Chimical
What is the name of the process of which evolution occurs?
The best answer is death.
Where did evolution occur?
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
