How have organisms have changed over time?
Organisms have changed over time through a process called evolution, where genetic variations arise and those that provide a survival advantage are passed on to future generations. Environmental pressures and natural selection drive these changes, leading to the diversity of life we see today.
Scientists study the to learn about the history of life past environments on Earth and how different groups of organisms have changed over time.?
Scientists study fossils to learn about the history of life on Earth, past environments, and how different groups of organisms have evolved and changed over time. By analyzing fossil remains, scientists can reconstruct ancient ecosystems and understand how life has adapted to environmental changes over millions of years. This information helps us piece together the evolutionary timeline of life on Earth and how it has shaped the world we live in today.
At age 90 what is life expectancy with kidney cancer spread to bones spine and liver?
Life expectancy for a 90-year-old with kidney cancer spread to the bones, spine, and liver is generally poor, with a median survival time of around 6 to 12 months. Treatment options may focus on palliative care to manage symptoms and improve quality of life. It is important to discuss prognosis and care preferences with the healthcare team to make informed decisions.
Does the Theory of Evolution attempt to explain the origin of life?
No, the Theory of Evolution explains how life diversified and changed over time through mechanisms like natural selection. The origin of life is a separate question addressed by theories like abiogenesis.
Does evolution describe how life began?
No, evolution does not describe how life began. Evolution explains how life forms have changed and adapted over time through the process of natural selection, but it does not address the origin of life itself. The origin of life is a separate field of study known as abiogenesis.
