What scientist influenced Darwin?
Charles Lyell
Which of the following scientists influenced Darwin as he developed his ideas about evolution choose all that apply?
Thomas Malthus was arguably the person who was most influential to Darwin. Darwin applied these ideas to populations of all species and came up with the idea of “survival of the fittest”. Malthus’s ideas seemed to support all of the studying Darwin had done on the Galapagos finches and their beak adaptations.
Who did Darwin get his ideas from?
Natural Selection: Charles Darwin & Alfred Russel Wallace. A visit to the Galapagos Islands in 1835 helped Darwin formulate his ideas on natural selection. He found several species of finch adapted to different environmental niches.
Which type of cells existed first?
The first cells were most likely primitive prokaryotic-like cells, even more simplistic than these E. coli bacteria. The first cells were probably no more than organic compounds, such as a simplistic RNA, surrounded by a membrane.
How did multicellular life begin?
The first evidence of multicellularity is from cyanobacteria-like organisms that lived 3–3.5 billion years ago. To reproduce, true multicellular organisms must solve the problem of regenerating a whole organism from germ cells (i.e., sperm and egg cells), an issue that is studied in evolutionary developmental biology.
How did we grow from one cell to a whole person?
Over the course of hours, days, or months, the organism turns from a single cell called the zygote (the product of sperm meeting egg) into a huge, organized collection of cells, tissues, and organs. As an embryo develops, its cells divide, grow, and migrate in specific patterns to make a more and more elaborate body.
Does all life share a common ancestor?
All life on Earth shares a single common ancestor, a new statistical analysis confirms. Because microorganisms of different species often swap genes, some scientists have proposed that multiple primordial life forms could have tossed their genetic material into life’s mix, creating a web, rather than a tree of life.
