Paleoanthropology uses the fossil record to examine the anatomy and behavior of our relatives in the past.
What is Paleoanthropology?
- By reconstructing evolutionary kinship lines within the family Hominidae using biological evidence (such as petrified skeletal remains, bone fragments, and footprints), paleoanthropology, also known as paleo-anthropology, seeks to understand the early development of anatomically modern humans, also known as hominization (such as stone tools, artifacts, and settlement localities).
- Primatology, palaeontology, biological anthropology, and cultural anthropology are all combined in one area.
- Genetics is becoming more and more important as technology and methodologies progress, especially when it comes to analysing and comparing DNA structure as a crucial tool for studying the evolutionary kinship lines of related species and genera.

From what we know, we can confirm that an invasive species will be the one that when introduced into an environment, reproduces at a rate that harms the biodiversity of the local ecosystem.
<h3 /><h3>What is the harm of these species to ecosystems?</h3>
Invasive species harm ecosystems greatly. Though invasive species are often rare, they cause great harm to ecosystems by affecting the biodiversity of the system and can lead to widespread extinctions of other organisms in that particular ecosystem.
Therefore, an invasive species will be the one that when introduced into an environment, reproduces at a rate that harms the biodiversity of the local ecosystem.

Answer:
all member are same species
Multiple methods of reproduction support the longevity of sponges in the fossil record is described below.
Explanation:
Sponges are able to reproduce both sexually using gametes and asexually by budding. Even though sponges are hermaphroditic, individuals will only make one type of gamete at a time. There are two forms of asexual reproduction that sponges can go through: external budding and internal budding.
Sponges reproduce sexually, too. Sponges do not have separate sexes-a single sponge forms eggs at one time of the year and sperm at a different time. At any one time of the year, some sponges are producing eggs and others are producing sperm.
The volume of water passing through a sponge can be enormous, up to 20,000 times its volume in a single 24 hour period.
Sponges reproduce by both asexual and sexual means. Most poriferans that reproduce by sexual means are hermaphroditic and produce eggs and sperm at different times. Sperm are frequently "broadcast" into the water column. ... Some sponges release their larvae, where others retain them for some time.
