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.

What is the process by which living things change over a period of time?
The process by which living things change over a period of time is called evolution. Evolution occurs through natural selection, genetic variation, and environmental pressures, leading to changes in the genetic makeup of populations over successive generations.
What part of the cell theory did Lynn margulis contribute to?
She concluded that some organelles found in eukaryotes were once free-living prokaryotes.
According to evolution evolution generally occurs when?
evolution generally occurs when there are genetic variations within a population that provide a survival advantage in a particular environment. Those individuals with advantageous traits are more likely to survive, reproduce, and pass on these traits to their offspring, leading to a change in the gene pool over generations.
What is a name given for genetic changes in living things over time?
The name given for genetic changes in living things over time is called evolution. This process occurs through natural selection, genetic drift, and other mechanisms, leading to the diversity of life forms we see today.
Is it possible for granite to have fossils or shells in it?
Yes, it is possible for granite to contain fossils or shells. This occurs when sedimentary rocks containing fossils or shells are metamorphosed and transformed into granite over time. The original fossils or shells may be preserved within the granite, although they may be altered or distorted due to the intense heat and pressure of the metamorphic process.
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.
The smallest unit in which evolution occurs is?
The smallest unit in which evolution occurs is a population.
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 is the process by which living things change over a period of time?
The process by which living things change over a period of time is called evolution. Evolution occurs through natural selection, genetic variation, and environmental pressures, leading to changes in the genetic makeup of populations over successive generations.
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.
Does evolution occur in individuals or in population?
Evolution occurs in population not in an individual.
Occurs when species that were similar become increasingly distinct?
Divergent evolution:)
What type of reaction occurs to fossils under pressure in the sediment?
Chimical
How does biological evolution differ from chemical evolution?
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
What is the name of the process of which evolution occurs?
The best answer is death.
Do you think that evolution by natural selection is occurring in cacti?
Evolution occurs in all life, all the time.
